1Vivante GPU core devices 2======================== 3 4Required properties: 5- compatible: Should be "vivante,gc" 6 A more specific compatible is not needed, as the cores contain chip 7 identification registers at fixed locations, which provide all the 8 necessary information to the driver. 9- reg: should be register base and length as documented in the 10 datasheet 11- interrupts: Should contain the cores interrupt line 12- clocks: should contain one clock for entry in clock-names 13 see Documentation/devicetree/bindings/clock/clock-bindings.txt 14- clock-names: 15 - "bus": AXI/master interface clock 16 - "reg": AHB/slave interface clock 17 (only required if GPU can gate slave interface independently) 18 - "core": GPU core clock 19 - "shader": Shader clock (only required if GPU has feature PIPE_3D) 20 21Optional properties: 22- power-domains: a power domain consumer specifier according to 23 Documentation/devicetree/bindings/power/power_domain.txt 24 25example: 26 27gpu_3d: gpu@130000 { 28 compatible = "vivante,gc"; 29 reg = <0x00130000 0x4000>; 30 interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>; 31 clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>, 32 <&clks IMX6QDL_CLK_GPU3D_CORE>, 33 <&clks IMX6QDL_CLK_GPU3D_SHADER>; 34 clock-names = "bus", "core", "shader"; 35 power-domains = <&gpc 1>; 36}; 37
