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:
+ "amlogic,meson-gxm-mali"
+ "rockchip,rk3288-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.
- 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/power/opp.txt
for details.
Example for a Mali-T760:
gpu@ffa30000 {
compatible = "rockchip,rk3288-mali", "arm,mali-t760", "arm,mali-midgard";
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>;
};
gpu_opp_table: opp_table0 {
compatible = "operating-points-v2";
opp@533000000 {
opp-hz = /bits/ 64 <533000000>;
opp-microvolt = <1250000>;
};
opp@450000000 {
opp-hz = /bits/ 64 <450000000>;
opp-microvolt = <1150000>;
};
opp@400000000 {
opp-hz = /bits/ 64 <400000000>;
opp-microvolt = <1125000>;
};
opp@350000000 {
opp-hz = /bits/ 64 <350000000>;
opp-microvolt = <1075000>;
};
opp@266000000 {
opp-hz = /bits/ 64 <266000000>;
opp-microvolt = <1025000>;
};
opp@160000000 {
opp-hz = /bits/ 64 <160000000>;
opp-microvolt = <925000>;
};
opp@100000000 {
opp-hz = /bits/ 64 <100000000>;
opp-microvolt = <912500>;
};
};
