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>;
};
