Kernel-4.18.0-80.el8_etnaviv-dr

Vivante GPU core devices

Required properties:

• compatible: Should be “vivante,gc”
  A more specific compatible is not needed, as the cores contain chip
  identification registers at fixed locations, which provide all the
  necessary information to the driver.
• reg: should be register base and length as documented in the
  datasheet
• interrupts: Should contain the cores interrupt line
• clocks: should contain one clock for entry in clock-names
  see Documentation/devicetree/bindings/clock/clock-bindings.txt
• clock-names:
  • “bus”: AXI/master interface clock
  • “reg”: AHB/slave interface clock

          (only required if GPU can gate slave interface independently)
    

  • “core”: GPU core clock
  • “shader”: Shader clock (only required if GPU has feature PIPE_3D)

Optional properties:

• power-domains: a power domain consumer specifier according to
  Documentation/devicetree/bindings/power/power_domain.txt

example:

gpu_3d: gpu@130000 {
compatible = “vivante,gc”;
reg = <0x00130000 0x4000>;
interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,
<&clks IMX6QDL_CLK_GPU3D_CORE>,
<&clks IMX6QDL_CLK_GPU3D_SHADER>;
clock-names = “bus”, “core”, “shader”;
power-domains = <&gpc 1>;
};
