Subject: [PATCH 01/39] ARM64: dts: meson-gxm: Add support for Khadas VIM2
The Khadas VIM2 is a Single Board Computer, respin of the origin
Khadas VIM board, using an Amlogic S912 SoC and more server oriented.
It provides the same external connectors and header pinout, plus a SPI
NOR Flash, a reprogrammable STM8S003 MCU, FPC Connector, Cooling FAN header
and Pogo Pads Arrays.

Subject: [PATCH 04/39] phy: meson: add USB3 PHY support for Meson GXL
This adds USB3 PHY driver found on Meson GXL and GXM SoCs.
Unfortunately there are no datasheets available for any of these PHYs.
Both drivers were written by reading the reference drivers provided by
Amlogic and analyzing the registers on the kernel that was shipped with
my board.

Subject: [PATCH 05/39] usb: host: add a generic platform USB roothub driver
Many SoC platforms have separate devices for the USB PHY which are
registered through the generic PHY framework. These PHYs have to be
enabled to make the USB controller actually work. They also have to be
disabled again on shutdown/suspend.
Currently (at least) the following HCI platform drivers are using custom
code to obtain all PHYs via devicetree for the roothub/controller and
disable/enable them when required:
- ehci-platform.c has ehci_platform_power_{on,off}
- xhci-mtk.c has xhci_mtk_phy_{init,exit,power_on,power_off}
- ohci-platform.c has ohci_platform_power_{on,off}
These drivers are not using the generic devicetree USB device bindings
yet which were only introduced recently (documentation is available in
devicetree/bindings/usb/usb-device.txt).
With this new driver the usb2-phy and usb3-phy can be specified directly
in the child-node of the corresponding port of the roothub via
devicetree. This can be extended by not just parsing PHYs (some of the
other drivers listed above are for example also parsing a list of clocks
as well) when required.

+Generic USB root-hub Properties
+
+similar to the USB device bindings (documented in usb-device.txt from the
+current directory) this provides support for configuring the root-hub.
+
+Required properties:
+- compatible: should be at least one of "usb1d6b,3", "usb1d6b,2"
+- reg: must be 0.
+- address-cells: must be 1
+- size-cells: must be 0
+
+Required sub-nodes:
+a sub-node per actual USB port is required. each sub-node supports the
+following properties:
+ Required properties:
+ - reg: the port number on the root-hub (mandatory)
+ Optional properties:
+ - phys: optional, from the *Generic PHY* bindings (mandatory needed
+ when phy-names is given)
+ - phy-names: optional, from the *Generic PHY* bindings; supported names
+ are "usb2-phy" or "usb3-phy"
+
+Example:
+ &usb1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ roothub@0 {
+ compatible = "usb1d6b,3", "usb1d6b,2";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ port@1 {
+ reg = <1>;
+ usb-phy = <&usb2_phy1>, <&usb3_phy1>;
+ phy-names = "usb2-phy", "usb3-phy";
+ };
+
+ port@2 {
+ reg = <2>;
+ usb-phy = <&usb2_phy2>, <&usb3_phy2>;
+ phy-names = "usb2-phy", "usb3-phy";

Subject: [PATCH 06/39] usb: host: xhci: plat: integrate the platform-roothub
This enables the platform-roothub for the xhci-plat driver. This allows
specifying a PHY for each port via devicetree. All PHYs will then be
enabled/disabled by the platform-roothub driver.
One example where this is required is the Amlogic GXL and GXM SoCs:
They are using a dwc3 USB controller with up to three ports enabled on
the internal roothub. Using only the top-level "phy" properties does not
work here since one can only specify one "usb2-phy" and one "usb3-phy",
while actually at least two "usb2-phy" have to be specified.

Subject: [PATCH 07/39] ARM64: dts: meson-gxl: add USB host support
This adds USB host support to the Meson GXL SoC. A dwc3 controller is
used for host-mode, while a dwc2 controller is used for device-mode only.
The dwc3 controller's internal roothub has two USB2 ports enabled but no
USB3 port. Each of the ports is supplied by a separate PHY. The USB pins
are connected to the SoC's USBHOST_A and USBOTG_B pins.
Due to the way the roothub works internally the USB PHYs are left
enabled. When the dwc3 controller is disabled the PHY is never powered on
so it does not draw any extra power. However, when the dwc3 host
controller is enabled then all PHYs also have to be enabled, otherwise
USB devices will not be detected (regardless of whether they are plugged
into an enabled port or not). This means that only the dwc3 controller
has to be enabled on boards with USB support (instead of requiring all
boards to enable the PHYs additionally with the chance of forgetting to
enable one and breaking all other ports with that as well).

Subject: [PATCH 08/39] ARM64: dts: meson-gxm: add GXM specific USB host
configuration
The USB configuration on GXM is slightly different than on GXL. The dwc3
controller's internal hub has three USB2 ports (instead of 2 on GXL)
along with a dedicated USB2 PHY for this port. However, it seems that
there are no pins on GXM which would allow connecting the third port to
a physical USB port.

Subject: [PATCH 32/39] ARM64: dts: meson-gx: Add HDMI_5V regulator on selected
boards
On reference boards and derivatives, the HDMI Logic is powered by an external
5V regulator.
This regulator was set by the Vendor U-Boot, add the regulator and phandle
property to the HDMI node.

From 9afb9faf483008a1d16202818d895099e5c932bb Mon Sep 17 00:00:00 2001
From: Jerome Brunet <jbrunet@baylibre.com>
Date: Fri, 8 Dec 2017 12:08:11 +0100
Subject: [PATCH 36/39] net: phy: meson-gxl: detect LPA corruption
The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)
This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.
To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.
The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.
Fixes: 7334b3e47aee ("net: phy: Add Meson GXL Internal PHY driver")
