- 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"
- + "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.
- - 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.
- Example for a Mali-T760:
- gpu@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>;
- };
- 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-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>;
- };
- };
