-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
-
-Example for a Mali-T760:
-
-gpu at ffa30000 {
- compatible = "rockchip,rk3288-mali", "arm,mali-t760";
- reg = <0xffa30000 0x10000>;
- interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "job", "mmu", "gpu";
- clocks = <&cru ACLK_GPU>;
- mali-supply = <&vdd_gpu>;
- operating-points-v2 = <&gpu_opp_table>;
- power-domains = <&power RK3288_PD_GPU>;
- #cooling-cells = <2>;
-};
-
-gpu_opp_table: opp_table0 {
- compatible = "operating-points-v2";
