1 Etnaviv DRM master device
2 =========================
4 The Etnaviv DRM master device is a virtual device needed to list all
5 Vivante GPU cores that comprise the GPU subsystem.
8 - compatible: Should be one of
9 "fsl,imx-gpu-subsystem"
10 "marvell,dove-gpu-subsystem"
11 - cores: Should contain a list of phandles pointing to Vivante GPU devices
16 compatible = "fsl,imx-gpu-subsystem";
17 cores = <&gpu_2d>, <&gpu_3d>;
21 Vivante GPU core devices
22 ========================
25 - compatible: Should be "vivante,gc"
26 A more specific compatible is not needed, as the cores contain chip
27 identification registers at fixed locations, which provide all the
28 necessary information to the driver.
29 - reg: should be register base and length as documented in the
31 - interrupts: Should contain the cores interrupt line
32 - clocks: should contain one clock for entry in clock-names
33 see Documentation/devicetree/bindings/clock/clock-bindings.txt
35 - "bus": AXI/register clock
36 - "core": GPU core clock
37 - "shader": Shader clock (only required if GPU has feature PIPE_3D)
40 - power-domains: a power domain consumer specifier according to
41 Documentation/devicetree/bindings/power/power_domain.txt
46 compatible = "vivante,gc";
47 reg = <0x00130000 0x4000>;
48 interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
49 clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,
50 <&clks IMX6QDL_CLK_GPU3D_CORE>,
51 <&clks IMX6QDL_CLK_GPU3D_SHADER>;
