Subject: [PATCH] UPSTREAM: net: phy: realtek: fix enabling of the TX-delay for
RTL8211F
The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
PHY driver to enable the RX and/or TX delays:
- PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
PHY (if required, the MAC should add the delays in this case)
- PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
(currently not supported by RTL8211F)
With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
and PHY_INTERFACE_MODE_RGMII_TXID.
Additionally we now explicity disable the TX-delay, which seems to be
enabled automatically after a hard-reset of the PHY (by triggering it's
reset pin) to get a consistent state (as defined by the phy-mode).
This fixes a compatibility problem with some SoCs where the TX-delay was
also added by the MAC. With the TX-delay being applied twice the TX
clock was off and TX traffic was broken or very slow (<10Mbit/s) on
1000Mbit/s links.

Subject: [PATCH] UPSTREAM: net: phy: realtek: fix RTL8211F interrupt mode
After commit b94d22d94ad22 "ARM64: dts: meson-gx: add external PHY
interrupt on some platforms" ethernet stopped working on my Odroid-C2
which has a RTL8211F phy.
It turned out that no interrupts were triggered. Further analysis
showed the register INER can't be altered on page 0.
Because register INSR needs to be accessed via page 0xa43 I assumed
that register INER needs to be accessed via some page too.
Some brute force check resulted in page 0xa42 being the right one.
With this patch the phy is working properly in interrupt mode.

Subject: [PATCH] UPSTREAM: net: phy: realtek: add utility functions to
read/write page addresses
Realtek PHYs implement the concept of so-called "extension pages". The
reason for this is probably because these PHYs expose more registers
than available in the standard address range.
After all read/write operations on such a page are done the driver
should switch back to page 0 where the standard MII registers (such as
MII_BMCR) are available.
When referring to such a register the datasheets of RTL8211E and
RTL8211F always specify:
- the page / "ext. page" which has to be written to RTL821x_PAGE_SELECT
- an address (sometimes also called reg)
These new utility functions make the existing code easier to read since
it removes some duplication (switching back to page 0 is done within the
new helpers for example).
No functional changes are intended.

Subject: [PATCH] FROMLIST: net: phy: realtek: add support for configuring the
RX delay on RTL8211F
On RTL8211F the RX delay can also be enabled/disabled.
The overall behavior of the RX delay is similar to the behavior of the
TX delay, which was already supported by the driver.
The RX delay (similar to the TX delay) may be enabled using hardware pin
strapping. If the MAC already configures the RX delay (if required) then
the RX delay generated by the RTL8211F PHY has to be turned off.
While here, update the comment regarding the TX delay why it has to be
enabled or disabled within the driver.
Also avoid code-duplication by extracting the code to mask/unmask bits
in a paged register into a new rtl8211x_page_mask_bits helper function.

Subject: [PATCH] FROMLIST: net: phy: realtek: configure the INTB pin on
RTL8211F
The interrupt pin on the RTL8211F PHY can be used in two different
modes:
INTB
- the default mode of the PHY
- interrupts can be configured through page 0xa42 register RTL821x_INER
- interrupts can be ACK'ed through RTL8211F_INSR
- it acts as a level-interrupt which is active low
- Wake-on-LAN "wakeup" status is available in RTL8211F_INSR bit 7
PMEB:
- special mode for Wake-on-LAN
- interrupts configured through page 0xa42 register RTL821x_INER are
disabled
- it supports a "pulse low" waveform for the interrupt
For now we simply force the pin into INTB mode since the PHY driver does
not support Wake-on-LAN yet.

Subject: [PATCH] UPSTREAM: mmc: pwrseq: convert to proper platform device
simple-pwrseq and emmc-pwrseq drivers rely on platform_device
structure from of_find_device_by_node(), this works mostly. But, as there
is no driver associated with this devices, cases like default/init pinctrl
setup would never be performed by pwrseq. This becomes problem when the
gpios used in pwrseq require pinctrl setup.
Currently most of the common pinctrl setup is done in
drivers/base/pinctrl.c by pinctrl_bind_pins().
There are two ways to solve this issue on either convert pwrseq drivers
to a proper platform drivers or copy the exact code from
pcintrl_bind_pins(). I prefer converting pwrseq to proper drivers so that
other cases like setting up clks/parents from dt would also be possible.

Subject: [PATCH] UPSTREAM: mmc: pwrseq-simple: Add an optional
post-power-on-delay
Some devices need a while to boot their firmware after providing clks /
de-asserting resets before they are ready to receive sdio commands.
This commits adds a post-power-on-delay-ms devicetree property to
mmc-pwrseq-simple for use with such devices.

Subject: [PATCH] UPSTREAM: mmc: dt: pwrseq-simple: Invent power-off-delay-us
During power off, after the GPIO pin has been asserted, some devices like
the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
clock gating and turning off regulators as to follow a graceful shutdown
sequence.
Therefore invent an optional power-off-delay-us DT binding for
mmc-pwrseq-simple, to allow us to support this constraint.

mmc_set_signal_voltage()
The mmc_set_signal_voltage() function is used for SD/SDIO when switching to
1.8V for UHS mode. To clarify this let's do the following changes.
- We are always providing MMC_SIGNAL_VOLTAGE_180 as the signal_voltage
parameter to the function. Then, let's just remove the parameter as it
serves no purpose.
- Rename the function to mmc_set_uhs_voltage().

Subject: [PATCH] UPSTREAM: mmc: sd: Fix signal voltage when there is no power
cycle
Some boards have SD card connectors where the power rail cannot be switched
off by the driver. However there are various circumstances when a card
might be re-initialized, such as after system resume, warm re-boot, or
error handling. However, a UHS card will continue to use 1.8V signaling
unless it is power cycled.
If the card has not been power cycled, it may still be using 1.8V
signaling. According to the SD spec., the Bus Speed Mode (function group 1)
bits 2 to 4 are zero if the card is initialized at 3.3V signal level. Thus
they can be used to determine if the card has already switched to 1.8V
signaling. Detect that situation and try to initialize a UHS-I (1.8V)
transfer mode.
Tested with the following cards:
Transcend 4GB High Speed
Kingston 64GB SDR104
Lexar by Micron HIGH-PERFORMANCE 300x 16GB DDR50
SanDisk Ultra 8GB DDR50
Transcend Ultimate 600x 16GB SDR104
Transcend Premium 300x 64GB SDR104
Lexar by Micron Professional 1000x 32GB UHS-II SDR104
SanDisk Extreme Pro 16GB SDR104

Subject: [PATCH] UPSTREAM: add basic register-field manipulation macros
Common approach to accessing register fields is to define
structures or sets of macros containing mask and shift pair.
Operations on the register are then performed as follows:
field = (reg >> shift) & mask;
reg &= ~(mask << shift);
reg |= (field & mask) << shift;
Defining shift and mask separately is tedious. Ivo van Doorn
came up with an idea of computing them at compilation time
based on a single shifted mask (later refined by Felix) which
can be used like this:
#define REG_FIELD 0x000ff000
field = FIELD_GET(REG_FIELD, reg);
reg &= ~REG_FIELD;
reg |= FIELD_PREP(REG_FIELD, field);
FIELD_{GET,PREP} macros take care of finding out what the
appropriate shift is based on compilation time ffs operation.
GENMASK can be used to define registers (which is usually
less error-prone and easier to match with datasheets).
This approach is the most convenient I've seen so to limit code
multiplication let's move the macros to a global header file.
Attempts to use static inlines instead of macros failed due
to false positive triggering of BUILD_BUG_ON()s, especially with
GCC < 6.0.

There were a couple messed up things about this fail path.
(1) it would drop object_name_lock twice
(2) drm_gem_handle_delete() (in drm_gem_remove_prime_handles())
needs to grab prime_lock

Subject: [PATCH] UPSTREAM: drm: Convert prime dma-buf <-> handle to rbtree
Currently we use a linear walk to lookup a handle and return a dma-buf,
and vice versa. A long overdue TODO task is to convert that to a
hashtable. Since the initial implementation of dma-buf/prime, we now
have resizeable hashtables we can use (and now a future task is to RCU
enable the lookup!). However, this patch opts to use an rbtree instead
to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen
over using the RCU backed resizable hashtable to firstly avoid the
reallocations (rbtrees can be embedded entirely within the parent
struct) and to favour simpler code with predictable worst case
behaviour. In simple testing, the difference between using the constant
lookup and insertion of the rhashtable and the rbtree was less than 10%
of the wall time (igt/benchmarks/prime_lookup) - both are dramatic
improvements over the existing linear lists.
v2: Favour rbtree over rhashtable

Subject: [PATCH] UPSTREAM: drm/prime: Take a ref on the drm_dev when exporting
a dma_buf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
dma_buf may live a long time, longer than the last direct user of the
driver. We already hold a reference to the owner module (that prevents
the object code from disappearing), but there is no reference to the
drm_dev - so the pointers to the driver backend themselves may vanish.
v2: Resist temptation to fix the bug in armada_gem.c not setting the
correct flags on the exported dma-buf (it should pass the flags through
and not be arbitrarily setting O_RDWR).
Use a common wrapper for exporting the dmabuf and acquiring the
reference to the drm_device.

Subject: [PATCH] UPSTREAM: drm: Take ownership of the dmabuf->obj when
exporting
Currently the reference for the dmabuf->obj is incremented for the
dmabuf in drm_gem_prime_handle_to_fd() (at the high level userspace
interface), but is released in drm_gem_dmabuf_release() (the lowlevel
handler). Improve the symmetry of the dmabuf->obj ownership by acquiring
the reference in drm_gem_dmabuf_export(). This makes it easier to use
the prime functions directly.

Subject: [PATCH] UPSTREAM: drm/prime: skip CPU sync in map/unmap dma_buf
Dma-bufs should already be device coherent, as they are only pulled in the
CPU domain via the begin/end cpu_access calls. As we cache the mapping set
up by dma_map_sg a CPU sync at this point will not actually guarantee proper
coherency on non-coherent architectures, so we can as well stop pretending.
This is an important performance fix for architectures which need explicit
cache synchronization and userspace doing lots of dma-buf imports.
Improves Weston on Etnaviv performance 5x, where before this patch > 90%
of Weston CPU time was spent synchronizing caches for buffers which are
already device coherent.

Subject: [PATCH] UPSTREAM: drm: Release driver tracking before making the
object available again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is the same bug as we fixed in commit f6cd7daecff5 ("drm: Release
driver references to handle before making it available again"), but now
the exposure is via the PRIME lookup tables. If we remove the
object/handle from the PRIME lut, then a new request for the same
object/fd will generate a new handle, thus for a short window that
object is known to userspace by two different handles. Fix this by
releasing the driver tracking before PRIME.
Fixes: 0ff926c7d4f0 ("drm/prime: add exported buffers to current fprivs
