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>;
|
||||
};
