Device Tree makes it possible -+to support many hardware configurations with a single kernel and without the -+need to explicitly load or blacklist kernel modules. Note that this isn't a -+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices -+are still configured by the board support code, but the intention is to -+eventually reach that goal. -+ -+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By -+default, the Raspberry Pi kernel boots with device tree enabled. You can -+completely disable DT usage (for now) by adding: -+ -+ device_tree= -+ -+to your config.txt, which should cause your Pi to revert to the old way of -+doing things after a reboot. -+ -+In /boot you will find a .dtb for each base platform. This describes the -+hardware that is part of the Raspberry Pi board. The loader (start.elf and its -+siblings) selects the .dtb file appropriate for the platform by name, and reads -+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) -+are disabled, but they can be enabled using Device Tree parameters: -+ -+ dtparam=i2c=on,i2s=on,spi=on -+ -+However, this shouldn't be necessary in many use cases because loading an -+overlay that requires one of those interfaces will cause it to be enabled -+automatically, and it is advisable to only enable interfaces if they are -+needed. -+ -+Configuring additional, optional hardware is done using Device Tree overlays -+(see below). -+ -+raspi-config -+============ -+ -+The Advanced Options section of the raspi-config utility can enable and disable -+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it -+is possible to both enable an interface and blacklist the driver, if for some -+reason you should want to defer the loading. -+ -+Modules -+======= -+ -+As well as describing the hardware, Device Tree also gives enough information -+to allow suitable driver modules to be located and loaded, with the corollary -+that unneeded modules are not loaded. As a result it should be possible to -+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can -+have its contents deleted (or commented out). -+ -+Using Overlays -+============== -+ -+Overlays are loaded using the "dtoverlay" directive. As an example, consider -+the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the -+pre-DT world this would be loaded from /etc/modules, with an explicit -+"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, -+this becomes a line in config.txt: -+ -+ dtoverlay=lirc-rpi -+ -+This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By -+default it will use GPIOs 17 (out) and 18 (in), but this can be modified using -+DT parameters: -+ -+ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 -+ -+Parameters always have default values, although in some cases (e.g. "w1-gpio") -+it is necessary to provided multiple overlays in order to get the desired -+behaviour. See the list of overlays below for a description of the parameters -+and their defaults. -+ -+The Overlay and Parameter Reference -+=================================== -+ -+N.B.

By creating -special case functions for 16bpp and 32bpp, by far the most common pixel -formats used on modern systems, a significant speed-up is attained -which can be readily felt on ARM-based devices like the Raspberry Pi -and the Allwinner platform, but should help any platform using the -fb layer. - -The special case functions allow constant folding, eliminating a number -of instructions including divide operations, and allow the use of an -unrolled loop, eliminating instructions with a variable shift size, -reducing source memory access instructions, and eliminating excessive -branching. These unrolled loops also allow much better code optimization -by the C compiler. The code that selects which optimized variant is used -is also simplified, eliminating integer divide instructions. - -The speed-up, measured by timing 'cat file.txt' in the console, varies -between 40% and 70%, when testing on the Raspberry Pi and Allwinner -ARM-based platforms, depending on font size and the pixel depth, with -the greater benefit for 32bpp. - -Signed-off-by: Harm Hanemaaijer ---- - drivers/video/fbdev/core/cfbimgblt.c | 152 +++++++++++++++++++++++++++++++++-- - 1 file changed, 147 insertions(+), 5 deletions(-) - -diff --git a/drivers/video/fbdev/core/cfbimgblt.c b/drivers/video/fbdev/core/cfbimgblt.c -index a2bb276..436494f 100644 ---- a/drivers/video/fbdev/core/cfbimgblt.c -+++ b/drivers/video/fbdev/core/cfbimgblt.c -@@ -28,6 +28,11 @@ - * - * Also need to add code to deal with cards endians that are different than - * the native cpu endians.

At 192kHz only 128xfs is supported. The existing - driver selects 128xfs automatically for some lower samples rates. By using an - additional mclk_div divider, it is now possible to control the behaviour. - This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It - should allow lower jitter and better signal quality. The behavior has to be - controlled by the sound card driver, because some sample frequency share the - same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only - difference is the MCLK divider. - -This also added support for 32bit data. - -Signed-off-by: Daniel Matuschek ---- - sound/soc/codecs/wm8804.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - -diff --git a/sound/soc/codecs/wm8804.c b/sound/soc/codecs/wm8804.c -index 8d91470..5795fb1 100644 ---- a/sound/soc/codecs/wm8804.c -+++ b/sound/soc/codecs/wm8804.c -@@ -304,6 +304,7 @@ static int wm8804_hw_params(struct snd_pcm_substream *substream, - blen = 0x1; - break; - case 24: -+ case 32: - blen = 0x2; - break; - default: -@@ -515,7 +516,7 @@ static const struct snd_soc_dai_ops wm8804_dai_ops = { - }; - - #define WM8804_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S20_3LE | \ -- SNDRV_PCM_FMTBIT_S24_LE) -+ SNDRV_PCM_FMTBIT_S24_3LE | SNDRV_PCM_FMTBIT_S32_LE) - - #define WM8804_RATES (SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \ - SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_64000 | \ - -From 71ef415a7c7943f091f48f7cd7a1594ef43f7d6d Mon Sep 17 00:00:00 2001 -From: Daniel Matuschek -Date: Wed, 15 Jan 2014 21:42:08 +0100 -Subject: [PATCH 063/127] ASoC: BCM:Add support for HiFiBerry Digi.

trigger - -The "input" trigger makes the associated GPIO an input. This is to support -the Raspberry Pi PWR LED, which is driven by external hardware in normal use. - -N.B. pwr_led is not available on Model A or B boards. - -leds-gpio: Implement the brightness_get method - -The power LED uses some clever logic that means it is driven -by a voltage measuring circuit when configured as input, otherwise -it is driven by the GPIO output value. This patch wires up the -brightness_get method for leds-gpio so that user-space can monitor -the LED value via /sys/class/gpio/led1/brightness. Using the input -trigger this returns an indication of the system power health, -otherwise it is just whatever value the trigger has written most -recently. - -See: https://github.com/raspberrypi/linux/issues/1064 ---- - drivers/leds/leds-gpio.c | 18 +++++++++++- - drivers/leds/trigger/Kconfig | 7 +++++ - drivers/leds/trigger/Makefile | 1 + - drivers/leds/trigger/ledtrig-input.c | 54 ++++++++++++++++++++++++++++++++++++ - include/linux/leds.h | 3 ++ - 5 files changed, 82 insertions(+), 1 deletion(-) - create mode 100644 drivers/leds/trigger/ledtrig-input.c - -diff --git a/drivers/leds/leds-gpio.c b/drivers/leds/leds-gpio.c -index 61143f5..e98df59 100644 ---- a/drivers/leds/leds-gpio.c -+++ b/drivers/leds/leds-gpio.c -@@ -46,8 +46,15 @@ static void gpio_led_set(struct led_classdev *led_cdev, - led_dat->platform_gpio_blink_set(led_dat->gpiod, level, - NULL, NULL); - led_dat->blinking = 0; -+ } else if (led_dat->cdev.flags & SET_GPIO_INPUT) { -+ gpiod_direction_input(led_dat->gpiod); -+ led_dat->cdev.flags &= ~SET_GPIO_INPUT; -+ } else if (led_dat->cdev.flags & SET_GPIO_OUTPUT) { -+ gpiod_direction_output(led_dat->gpiod, level); -+ led_dat->cdev.flags &= ~SET_GPIO_OUTPUT; - } else { -- if (led_dat->can_sleep) -+ if (led_dat->can_sleep || -+ (led_dat->cdev.flags & (SET_GPIO_INPUT | SET_GPIO_OUTPUT) )) - gpiod_set_value_cansleep(led_dat->gpiod, level); - else - gpiod_set_value(led_dat->gpiod, level); -@@ -61,6 +68,13 @@ static int gpio_led_set_blocking(struct led_classdev *led_cdev, - return 0; - } - -+static enum led_brightness gpio_led_get(struct led_classdev *led_cdev) -+{ -+ struct gpio_led_data *led_dat = -+ container_of(led_cdev, struct gpio_led_data, cdev); -+ return gpiod_get_value_cansleep(led_dat->gpiod) ?

If the bitrate goes above, -videocore will either resample the audio or corrupt it due to -underruns. Supposedly the hardware isn't designed to output -higher rates, but it can still resample it down to supported -rates. - -Some code is based on ac97_pcm.c. - -rpi: update vc_vchi_audioserv_defs.h - -Add audioserv 3 extensions. The changes were taken from the paste -linked here: - -https://github.com/raspberrypi/linux/pull/1166#issuecomment-151917067 - -bcm2835: implement channel map API - -Report all layouts supported by the HDMI protocol to userspace. -Make the videocore set the correct layout according to the -userspace request. - -Some code taken from patch_hdmi.c. In particular, the HDMI channel -layout table was copied without changes - with the idea in mind that -hopefully it can be shared one day. Or at least updating it will be -simpler. - -In my tests, everything appears to work, except when outputting -FL FR RL RR. Then my receiver outputs RL on both the RL and RR -speakers, while RR is never heard. - -bcm2835: access controls under the audio mutex - -I don't think the ALSA framework provides any kind of automatic -synchronization within the control callbacks. We most likely need -to ensure this manually, so add locking around all access to shared -mutable data. In particular, bcm2835_audio_set_ctls() should -probably always be called under our own audio lock. - -bcm2835: always use 2/4/8 channels for multichannel layouts - -Pad the unused channels with NA. This means userspace needs to write -additional, silent padding channels, which is not ideal, but better -than noise. - -Works around noise at the following channel counts: 3, 5, 6, 7 - -bcm2835: only allow stereo if analogue jack is selected - -Sending more than 2 channels to videocore while outputting to analogue -mysteriously outputs heavy artifacts. So just paint it over with a -hack: if analogue is explicitly selected as destination, do not -reporting support for anything other than stereo. - -I'm not sure how to deal with the auto case (destination 0). There's -probably way to retrieve this and even to listen to plug events, but -I didn't find one yet, and it's probably not worth the trouble. Just -don't use this setting, I guess. Unless you like noise. - -Changing the setting while an audio stream is active also doesn't -work properly. We could probably interrupt running streams by -returning ENODEV or using kernel hotplug stuff (maybe), but that -also doesn't seem worth the trouble. - -bcm2835: interpolate audio delay - -It appears the GPU only sends us a message all 10ms to update -the playback progress. Other than this, the playback position -(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all. -Userspace will see jitter up to 10ms in the audio position. - -Make this a bit nicer for userspace by interpolating the -position using the CPU clock. - -I'm not sure if setting snd_pcm_runtime.delay is the right -approach for this. Or if there is maybe an already existing -mechanism for position interpolation in the ALSA core. - -I only set SNDRV_PCM_INFO_BATCH because this appears to remove -at least one situation snd_pcm_runtime.delay is used, so I have -to worry less in which place I have to update this field, or -how it interacts with the rest of ALSA. - -In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY. -One problem is that it requires sending a videocore message, and -waiting for a reply, which could make the implementation much -harder due to locking and synchronization requirements. ---- - sound/arm/bcm2835-ctl.c | 341 ++++++++++++++++++++++++++++++++++++- - sound/arm/bcm2835-pcm.c | 87 +++++++++- - sound/arm/bcm2835-vchiq.c | 13 ++ - sound/arm/bcm2835.h | 5 + - sound/arm/vc_vchi_audioserv_defs.h | 13 +- - 5 files changed, 447 insertions(+), 12 deletions(-) - -diff --git a/sound/arm/bcm2835-ctl.c b/sound/arm/bcm2835-ctl.c -index aad905f..e930718 100755 ---- a/sound/arm/bcm2835-ctl.c -+++ b/sound/arm/bcm2835-ctl.c -@@ -94,6 +94,9 @@ static int snd_bcm2835_ctl_get(struct snd_kcontrol *kcontrol, - { - struct bcm2835_chip *chip = snd_kcontrol_chip(kcontrol);

As a result, overrides (parameters) +must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB. + +mmc-overlay.dts (that switches back to the original mmc

Device Tree makes it possible ++to support many hardware configurations with a single kernel and without the ++need to explicitly load or blacklist kernel modules. Note that this isn't a ++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices ++are still configured by the board support code, but the intention is to ++eventually reach that goal. ++ ++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By ++default, the Raspberry Pi kernel boots with device tree enabled. You can ++completely disable DT usage (for now) by adding: ++ ++ device_tree= ++ ++to your config.txt, which should cause your Pi to revert to the old way of ++doing things after a reboot. ++ ++In /boot you will find a .dtb for each base platform. This describes the ++hardware that is part of the Raspberry Pi board. The loader (start.elf and its ++siblings) selects the .dtb file appropriate for the platform by name, and reads ++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) ++are disabled, but they can be enabled using Device Tree parameters: ++ ++ dtparam=i2c=on,i2s=on,spi=on ++ ++However, this shouldn't be necessary in many use cases because loading an ++overlay that requires one of those interfaces will cause it to be enabled ++automatically, and it is advisable to only enable interfaces if they are ++needed. ++ ++Configuring additional, optional hardware is done using Device Tree overlays ++(see below). ++ ++raspi-config ++============ ++ ++The Advanced Options section of the raspi-config utility can enable and disable ++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it ++is possible to both enable an interface and blacklist the driver, if for some ++reason you should want to defer the loading. ++ ++Modules ++======= ++ ++As well as describing the hardware, Device Tree also gives enough information ++to allow suitable driver modules to be located and loaded, with the corollary ++that unneeded modules are not loaded. As a result it should be possible to ++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can ++have its contents deleted (or commented out). ++ ++Using Overlays ++============== ++ ++Overlays are loaded using the "dtoverlay" directive. As an example, consider ++the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the ++pre-DT world this would be loaded from /etc/modules, with an explicit ++"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, ++this becomes a line in config.txt: ++ ++ dtoverlay=lirc-rpi ++ ++This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By ++default it will use GPIOs 17 (out) and 18 (in), but this can be modified using ++DT parameters: ++ ++ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 ++ ++Parameters always have default values, although in some cases (e.g. "w1-gpio") ++it is necessary to provided multiple overlays in order to get the desired ++behaviour. See the list of overlays below for a description of the parameters ++and their defaults. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++N.B.

By creating +special case functions for 16bpp and 32bpp, by far the most common pixel +formats used on modern systems, a significant speed-up is attained +which can be readily felt on ARM-based devices like the Raspberry Pi +and the Allwinner platform, but should help any platform using the +fb layer. + +The special case functions allow constant folding, eliminating a number +of instructions including divide operations, and allow the use of an +unrolled loop, eliminating instructions with a variable shift size, +reducing source memory access instructions, and eliminating excessive +branching. These unrolled loops also allow much better code optimization +by the C compiler. The code that selects which optimized variant is used +is also simplified, eliminating integer divide instructions. + +The speed-up, measured by timing 'cat file.txt' in the console, varies +between 40% and 70%, when testing on the Raspberry Pi and Allwinner +ARM-based platforms, depending on font size and the pixel depth, with +the greater benefit for 32bpp. + +Signed-off-by: Harm Hanemaaijer +--- + drivers/video/fbdev/core/cfbimgblt.c | 152 +++++++++++++++++++++++++++++++++-- + 1 file changed, 147 insertions(+), 5 deletions(-) + +diff --git a/drivers/video/fbdev/core/cfbimgblt.c b/drivers/video/fbdev/core/cfbimgblt.c +index a2bb276..436494f 100644 +--- a/drivers/video/fbdev/core/cfbimgblt.c ++++ b/drivers/video/fbdev/core/cfbimgblt.c +@@ -28,6 +28,11 @@ + * + * Also need to add code to deal with cards endians that are different than + * the native cpu endians.

Therefore even if initialisation fails, the driver will still be +loaded, but won't work. This patch fixes this. I2C communication error will now +reported correctly by a non-zero return code. + +HiFiBerry Amp: fix device-tree problems + +Some code to load the driver based on device-tree-overlays was missing.

Device Tree makes it possible -+to support many hardware configurations with a single kernel and without the -+need to explicitly load or blacklist kernel modules. Note that this isn't a -+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices -+are still configured by the board support code, but the intention is to -+eventually reach that goal. -+ -+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By -+default, the Raspberry Pi kernel boots with device tree enabled. You can -+completely disable DT usage (for now) by adding: -+ -+ device_tree= -+ -+to your config.txt, which should cause your Pi to revert to the old way of -+doing things after a reboot. -+ -+In /boot you will find a .dtb for each base platform. This describes the -+hardware that is part of the Raspberry Pi board. The loader (start.elf and its -+siblings) selects the .dtb file appropriate for the platform by name, and reads -+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) -+are disabled, but they can be enabled using Device Tree parameters: -+ -+ dtparam=i2c=on,i2s=on,spi=on -+ -+However, this shouldn't be necessary in many use cases because loading an -+overlay that requires one of those interfaces will cause it to be enabled -+automatically, and it is advisable to only enable interfaces if they are -+needed. -+ -+Configuring additional, optional hardware is done using Device Tree overlays -+(see below). -+ -+raspi-config -+============ -+ -+The Advanced Options section of the raspi-config utility can enable and disable -+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it -+is possible to both enable an interface and blacklist the driver, if for some -+reason you should want to defer the loading. -+ -+Modules -+======= -+ -+As well as describing the hardware, Device Tree also gives enough information -+to allow suitable driver modules to be located and loaded, with the corollary -+that unneeded modules are not loaded. As a result it should be possible to -+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can -+have its contents deleted (or commented out). -+ -+Using Overlays -+============== -+ -+Overlays are loaded using the "dtoverlay" directive. As an example, consider -+the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the -+pre-DT world this would be loaded from /etc/modules, with an explicit -+"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, -+this becomes a line in config.txt: -+ -+ dtoverlay=lirc-rpi -+ -+This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By -+default it will use GPIOs 17 (out) and 18 (in), but this can be modified using -+DT parameters: -+ -+ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 -+ -+Parameters always have default values, although in some cases (e.g. "w1-gpio") -+it is necessary to provided multiple overlays in order to get the desired -+behaviour. See the list of overlays below for a description of the parameters -+and their defaults. -+ -+The Overlay and Parameter Reference -+=================================== -+ -+N.B.

By creating -special case functions for 16bpp and 32bpp, by far the most common pixel -formats used on modern systems, a significant speed-up is attained -which can be readily felt on ARM-based devices like the Raspberry Pi -and the Allwinner platform, but should help any platform using the -fb layer. - -The special case functions allow constant folding, eliminating a number -of instructions including divide operations, and allow the use of an -unrolled loop, eliminating instructions with a variable shift size, -reducing source memory access instructions, and eliminating excessive -branching. These unrolled loops also allow much better code optimization -by the C compiler. The code that selects which optimized variant is used -is also simplified, eliminating integer divide instructions. - -The speed-up, measured by timing 'cat file.txt' in the console, varies -between 40% and 70%, when testing on the Raspberry Pi and Allwinner -ARM-based platforms, depending on font size and the pixel depth, with -the greater benefit for 32bpp. - -Signed-off-by: Harm Hanemaaijer ---- - drivers/video/fbdev/core/cfbimgblt.c | 152 +++++++++++++++++++++++++++++++++-- - 1 file changed, 147 insertions(+), 5 deletions(-) - -diff --git a/drivers/video/fbdev/core/cfbimgblt.c b/drivers/video/fbdev/core/cfbimgblt.c -index a2bb276..436494f 100644 ---- a/drivers/video/fbdev/core/cfbimgblt.c -+++ b/drivers/video/fbdev/core/cfbimgblt.c -@@ -28,6 +28,11 @@ - * - * Also need to add code to deal with cards endians that are different than - * the native cpu endians.

At 192kHz only 128xfs is supported. The existing - driver selects 128xfs automatically for some lower samples rates. By using an - additional mclk_div divider, it is now possible to control the behaviour. - This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It - should allow lower jitter and better signal quality. The behavior has to be - controlled by the sound card driver, because some sample frequency share the - same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only - difference is the MCLK divider. - -This also added support for 32bit data. - -Signed-off-by: Daniel Matuschek ---- - sound/soc/codecs/wm8804.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - -diff --git a/sound/soc/codecs/wm8804.c b/sound/soc/codecs/wm8804.c -index 8d91470..5795fb1 100644 ---- a/sound/soc/codecs/wm8804.c -+++ b/sound/soc/codecs/wm8804.c -@@ -304,6 +304,7 @@ static int wm8804_hw_params(struct snd_pcm_substream *substream, - blen = 0x1; - break; - case 24: -+ case 32: - blen = 0x2; - break; - default: -@@ -515,7 +516,7 @@ static const struct snd_soc_dai_ops wm8804_dai_ops = { - }; - - #define WM8804_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S20_3LE | \ -- SNDRV_PCM_FMTBIT_S24_LE) -+ SNDRV_PCM_FMTBIT_S24_3LE | SNDRV_PCM_FMTBIT_S32_LE) - - #define WM8804_RATES (SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \ - SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_64000 | \ - -From 71ef415a7c7943f091f48f7cd7a1594ef43f7d6d Mon Sep 17 00:00:00 2001 -From: Daniel Matuschek -Date: Wed, 15 Jan 2014 21:42:08 +0100 -Subject: [PATCH 063/127] ASoC: BCM:Add support for HiFiBerry Digi.

trigger - -The "input" trigger makes the associated GPIO an input. This is to support -the Raspberry Pi PWR LED, which is driven by external hardware in normal use. - -N.B. pwr_led is not available on Model A or B boards. - -leds-gpio: Implement the brightness_get method - -The power LED uses some clever logic that means it is driven -by a voltage measuring circuit when configured as input, otherwise -it is driven by the GPIO output value. This patch wires up the -brightness_get method for leds-gpio so that user-space can monitor -the LED value via /sys/class/gpio/led1/brightness. Using the input -trigger this returns an indication of the system power health, -otherwise it is just whatever value the trigger has written most -recently. - -See: https://github.com/raspberrypi/linux/issues/1064 ---- - drivers/leds/leds-gpio.c | 18 +++++++++++- - drivers/leds/trigger/Kconfig | 7 +++++ - drivers/leds/trigger/Makefile | 1 + - drivers/leds/trigger/ledtrig-input.c | 54 ++++++++++++++++++++++++++++++++++++ - include/linux/leds.h | 3 ++ - 5 files changed, 82 insertions(+), 1 deletion(-) - create mode 100644 drivers/leds/trigger/ledtrig-input.c - -diff --git a/drivers/leds/leds-gpio.c b/drivers/leds/leds-gpio.c -index 61143f5..e98df59 100644 ---- a/drivers/leds/leds-gpio.c -+++ b/drivers/leds/leds-gpio.c -@@ -46,8 +46,15 @@ static void gpio_led_set(struct led_classdev *led_cdev, - led_dat->platform_gpio_blink_set(led_dat->gpiod, level, - NULL, NULL); - led_dat->blinking = 0; -+ } else if (led_dat->cdev.flags & SET_GPIO_INPUT) { -+ gpiod_direction_input(led_dat->gpiod); -+ led_dat->cdev.flags &= ~SET_GPIO_INPUT; -+ } else if (led_dat->cdev.flags & SET_GPIO_OUTPUT) { -+ gpiod_direction_output(led_dat->gpiod, level); -+ led_dat->cdev.flags &= ~SET_GPIO_OUTPUT; - } else { -- if (led_dat->can_sleep) -+ if (led_dat->can_sleep || -+ (led_dat->cdev.flags & (SET_GPIO_INPUT | SET_GPIO_OUTPUT) )) - gpiod_set_value_cansleep(led_dat->gpiod, level); - else - gpiod_set_value(led_dat->gpiod, level); -@@ -61,6 +68,13 @@ static int gpio_led_set_blocking(struct led_classdev *led_cdev, - return 0; - } - -+static enum led_brightness gpio_led_get(struct led_classdev *led_cdev) -+{ -+ struct gpio_led_data *led_dat = -+ container_of(led_cdev, struct gpio_led_data, cdev); -+ return gpiod_get_value_cansleep(led_dat->gpiod) ?

If the bitrate goes above, -videocore will either resample the audio or corrupt it due to -underruns. Supposedly the hardware isn't designed to output -higher rates, but it can still resample it down to supported -rates. - -Some code is based on ac97_pcm.c. - -rpi: update vc_vchi_audioserv_defs.h - -Add audioserv 3 extensions. The changes were taken from the paste -linked here: - -https://github.com/raspberrypi/linux/pull/1166#issuecomment-151917067 - -bcm2835: implement channel map API - -Report all layouts supported by the HDMI protocol to userspace. -Make the videocore set the correct layout according to the -userspace request. - -Some code taken from patch_hdmi.c. In particular, the HDMI channel -layout table was copied without changes - with the idea in mind that -hopefully it can be shared one day. Or at least updating it will be -simpler. - -In my tests, everything appears to work, except when outputting -FL FR RL RR. Then my receiver outputs RL on both the RL and RR -speakers, while RR is never heard. - -bcm2835: access controls under the audio mutex - -I don't think the ALSA framework provides any kind of automatic -synchronization within the control callbacks. We most likely need -to ensure this manually, so add locking around all access to shared -mutable data. In particular, bcm2835_audio_set_ctls() should -probably always be called under our own audio lock. - -bcm2835: always use 2/4/8 channels for multichannel layouts - -Pad the unused channels with NA. This means userspace needs to write -additional, silent padding channels, which is not ideal, but better -than noise. - -Works around noise at the following channel counts: 3, 5, 6, 7 - -bcm2835: only allow stereo if analogue jack is selected - -Sending more than 2 channels to videocore while outputting to analogue -mysteriously outputs heavy artifacts. So just paint it over with a -hack: if analogue is explicitly selected as destination, do not -reporting support for anything other than stereo. - -I'm not sure how to deal with the auto case (destination 0). There's -probably way to retrieve this and even to listen to plug events, but -I didn't find one yet, and it's probably not worth the trouble. Just -don't use this setting, I guess. Unless you like noise. - -Changing the setting while an audio stream is active also doesn't -work properly. We could probably interrupt running streams by -returning ENODEV or using kernel hotplug stuff (maybe), but that -also doesn't seem worth the trouble. - -bcm2835: interpolate audio delay - -It appears the GPU only sends us a message all 10ms to update -the playback progress. Other than this, the playback position -(what SNDRV_PCM_IOCTL_DELAY will return) is not updated at all. -Userspace will see jitter up to 10ms in the audio position. - -Make this a bit nicer for userspace by interpolating the -position using the CPU clock. - -I'm not sure if setting snd_pcm_runtime.delay is the right -approach for this. Or if there is maybe an already existing -mechanism for position interpolation in the ALSA core. - -I only set SNDRV_PCM_INFO_BATCH because this appears to remove -at least one situation snd_pcm_runtime.delay is used, so I have -to worry less in which place I have to update this field, or -how it interacts with the rest of ALSA. - -In the future, it might be nice to use VC_AUDIO_MSG_TYPE_LATENCY. -One problem is that it requires sending a videocore message, and -waiting for a reply, which could make the implementation much -harder due to locking and synchronization requirements. ---- - sound/arm/bcm2835-ctl.c | 341 ++++++++++++++++++++++++++++++++++++- - sound/arm/bcm2835-pcm.c | 87 +++++++++- - sound/arm/bcm2835-vchiq.c | 13 ++ - sound/arm/bcm2835.h | 5 + - sound/arm/vc_vchi_audioserv_defs.h | 13 +- - 5 files changed, 447 insertions(+), 12 deletions(-) - -diff --git a/sound/arm/bcm2835-ctl.c b/sound/arm/bcm2835-ctl.c -index aad905f..e930718 100755 ---- a/sound/arm/bcm2835-ctl.c -+++ b/sound/arm/bcm2835-ctl.c -@@ -94,6 +94,9 @@ static int snd_bcm2835_ctl_get(struct snd_kcontrol *kcontrol, - { - struct bcm2835_chip *chip = snd_kcontrol_chip(kcontrol);

As a result, overrides (parameters) +must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB. + +mmc-overlay.dts (that switches back to the original mmc

Device Tree makes it possible ++to support many hardware configurations with a single kernel and without the ++need to explicitly load or blacklist kernel modules. Note that this isn't a ++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices ++are still configured by the board support code, but the intention is to ++eventually reach that goal. ++ ++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By ++default, the Raspberry Pi kernel boots with device tree enabled. You can ++completely disable DT usage (for now) by adding: ++ ++ device_tree= ++ ++to your config.txt, which should cause your Pi to revert to the old way of ++doing things after a reboot. ++ ++In /boot you will find a .dtb for each base platform. This describes the ++hardware that is part of the Raspberry Pi board. The loader (start.elf and its ++siblings) selects the .dtb file appropriate for the platform by name, and reads ++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) ++are disabled, but they can be enabled using Device Tree parameters: ++ ++ dtparam=i2c=on,i2s=on,spi=on ++ ++However, this shouldn't be necessary in many use cases because loading an ++overlay that requires one of those interfaces will cause it to be enabled ++automatically, and it is advisable to only enable interfaces if they are ++needed. ++ ++Configuring additional, optional hardware is done using Device Tree overlays ++(see below). ++ ++raspi-config ++============ ++ ++The Advanced Options section of the raspi-config utility can enable and disable ++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it ++is possible to both enable an interface and blacklist the driver, if for some ++reason you should want to defer the loading. ++ ++Modules ++======= ++ ++As well as describing the hardware, Device Tree also gives enough information ++to allow suitable driver modules to be located and loaded, with the corollary ++that unneeded modules are not loaded. As a result it should be possible to ++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can ++have its contents deleted (or commented out). ++ ++Using Overlays ++============== ++ ++Overlays are loaded using the "dtoverlay" directive. As an example, consider ++the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the ++pre-DT world this would be loaded from /etc/modules, with an explicit ++"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, ++this becomes a line in config.txt: ++ ++ dtoverlay=lirc-rpi ++ ++This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By ++default it will use GPIOs 17 (out) and 18 (in), but this can be modified using ++DT parameters: ++ ++ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 ++ ++Parameters always have default values, although in some cases (e.g. "w1-gpio") ++it is necessary to provided multiple overlays in order to get the desired ++behaviour. See the list of overlays below for a description of the parameters ++and their defaults. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++N.B.

By creating +special case functions for 16bpp and 32bpp, by far the most common pixel +formats used on modern systems, a significant speed-up is attained +which can be readily felt on ARM-based devices like the Raspberry Pi +and the Allwinner platform, but should help any platform using the +fb layer. + +The special case functions allow constant folding, eliminating a number +of instructions including divide operations, and allow the use of an +unrolled loop, eliminating instructions with a variable shift size, +reducing source memory access instructions, and eliminating excessive +branching. These unrolled loops also allow much better code optimization +by the C compiler. The code that selects which optimized variant is used +is also simplified, eliminating integer divide instructions. + +The speed-up, measured by timing 'cat file.txt' in the console, varies +between 40% and 70%, when testing on the Raspberry Pi and Allwinner +ARM-based platforms, depending on font size and the pixel depth, with +the greater benefit for 32bpp. + +Signed-off-by: Harm Hanemaaijer +--- + drivers/video/fbdev/core/cfbimgblt.c | 152 +++++++++++++++++++++++++++++++++-- + 1 file changed, 147 insertions(+), 5 deletions(-) + +diff --git a/drivers/video/fbdev/core/cfbimgblt.c b/drivers/video/fbdev/core/cfbimgblt.c +index a2bb276..436494f 100644 +--- a/drivers/video/fbdev/core/cfbimgblt.c ++++ b/drivers/video/fbdev/core/cfbimgblt.c +@@ -28,6 +28,11 @@ + * + * Also need to add code to deal with cards endians that are different than + * the native cpu endians.

Therefore even if initialisation fails, the driver will still be +loaded, but won't work. This patch fixes this. I2C communication error will now +reported correctly by a non-zero return code. + +HiFiBerry Amp: fix device-tree problems + +Some code to load the driver based on device-tree-overlays was missing.

As +a result, when the overlays were modified for dynamic loading and it +was discovered that the hifiberry-dac overlay didn't work any more, the +the rpi-dac overlay was also broken. + +The failure was caused by the fact that outside a bus, device names are +constructed from the concatenation of the path elements leading to it, +so moving the codec instantiation inside /soc caused the device name +to get a "soc" added, breaking ALSA's naming. + +See: http://forum.kodi.tv/showthread.php?tid=269814&pid=2349776#pid2349776 + +Signed-off-by: Phil Elwell +--- + arch/arm/boot/dts/overlays/rpi-dac-overlay.dts | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts b/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts +index 1523eae..a442c8f0 100644 +--- a/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts ++++ b/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts +@@ -13,7 +13,7 @@ + }; + + fragment@1 { +- target = <&soc>; ++ target-path = "/"; + __overlay__ { + pcm1794a-codec { + #sound-dai-cells = <0>;
