The coefficient can either be calculated from power measurements or derived by analysis. The dynamic power consumption of the GPU is proportional to the square of the Voltage (V) and the clock frequency (f). The coefficient is used to calculate the dynamic power as below - Pdyn = dynamic-power-coefficient * V^2 * f where voltage is in V, frequency is in MHz. required: - compatible - reg - interrupts - interrupt-names - clocks additionalProperties: false allOf: - if: properties: compatible: contains: const: allwinner,sun50i-h6-mali then: properties: clocks: minItems: 2 required: - clock-names - resets - if: properties: compatible: contains: const: amlogic,meson-gxm-mali then: properties: resets: minItems: 2 required: - resets examples: - | #include #include gpu@ffa30000 { compatible = "rockchip,rk3288-mali", "arm,mali-t760"; reg = <0xffa30000 0x10000>; interrupts = , , ; interrupt-names = "job", "mmu", "gpu"; clocks = <&cru 0>; mali-supply = <&vdd_gpu>; operating-points-v2 = <&gpu_opp_table>; power-domains = <&power 0>; #cooling-cells = <2>; }; gpu_opp_table: opp-table { 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>; }; }; ...
