-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-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
-
-Example for a Mali-T760:
-
-gpu@ffa30000 {
-	compatible = "rockchip,rk3288-mali", "arm,mali-t760";
-	reg = <0xffa30000 0x10000>;

The original bindings was wrong, In fact, clocks should be required here aswell. Same for bifrost and utgard...

Should I send a fixup patch ?

This series converts the various Arm Mali GPU bindings to use the DT schema format.

The Midgard and Bifrost bindings generate warnings on 'interrupt-names' because there's all different ordering. The Utgard binding generates warnings on Rockchip platforms because 'clock-names' order is reversed.

This series converts the various Arm Mali GPU bindings to use the DT schema format.

The Midgard and Bifrost bindings generate warnings on 'interrupt-names' because there's all different ordering. The Utgard binding generates warnings on Rockchip platforms because 'clock-names' order is reversed.

Are you planning on sending fixes for these, should I just change the ordering myself?
