Pull ARM Devicetree updates from Olof Johansson:
"We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM
Mali GPU devices added to device trees, since the DRM drivers have now
been merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Fixes and polish for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now
at feature parity with TX1"

ARM Mali Midgard GPU
|
|
====================
|
|
|
|
Required properties:
|
|
|
|
- compatible :
|
|
* Must contain one of the following:
|
|
+ "arm,mali-t604"
|
|
+ "arm,mali-t624"
|
|
+ "arm,mali-t628"
|
|
+ "arm,mali-t720"
|
|
+ "arm,mali-t760"
|
|
+ "arm,mali-t820"
|
|
+ "arm,mali-t830"
|
|
+ "arm,mali-t860"
|
|
+ "arm,mali-t880"
|
|
* which must be preceded by one of the following vendor specifics:
|
|
+ "allwinner,sun50i-h6-mali"
|
|
+ "amlogic,meson-gxm-mali"
|
|
+ "samsung,exynos5433-mali"
|
|
+ "rockchip,rk3288-mali"
|
|
+ "rockchip,rk3399-mali"
|
|
|
|
- reg : Physical base address of the device and length of the register area.
|
|
|
|
- interrupts : Contains the three IRQ lines required by Mali Midgard devices.
|
|
|
|
- interrupt-names : Contains the names of IRQ resources in the order they were
|
|
provided in the interrupts property. Must contain: "job", "mmu", "gpu".
|
|
|
|
|
|
Optional properties:
|
|
|
|
- clocks : Phandle to clock for the Mali Midgard device.
|
|
|
|
- clock-names : Specify the names of the clocks specified in clocks
|
|
when multiple clocks are present.
|
|
* core: clock driving the GPU itself (When only one clock is present,
|
|
assume it's this clock.)
|
|
* bus: bus clock for the GPU
|
|
|
|
- mali-supply : Phandle to regulator for the Mali device. Refer to
|
|
Documentation/devicetree/bindings/regulator/regulator.txt for details.
|
|
|
|
- operating-points-v2 : Refer to Documentation/devicetree/bindings/opp/opp.txt
|
|
for details.
|
|
|
|
- #cooling-cells: Refer to Documentation/devicetree/bindings/thermal/thermal.txt
|
|
for details.
|
|
|
|
- resets : Phandle of the GPU reset line.
|
|
|
|
Vendor-specific bindings
|
|
------------------------
|
|
|
|
The Mali GPU is integrated very differently from one SoC to
|
|
another. In order to accommodate those differences, you have the option
|
|
to specify one more vendor-specific compatible, among:
|
|
|
|
- "allwinner,sun50i-h6-mali"
|
|
Required properties:
|
|
- clocks : phandles to core and bus clocks
|
|
- clock-names : must contain "core" and "bus"
|
|
- resets: phandle to GPU reset line
|
|
|
|
- "amlogic,meson-gxm-mali"
|
|
Required properties:
|
|
- resets : Should contain phandles of :
|
|
+ GPU reset line
|
|
+ GPU APB glue reset line
|
|
|
|
