[PATCH v3] dt-bindings: display: Convert etnaviv to json-schema

From: Benjamin Gaignard
Date: Wed Jan 29 2020 - 03:56:51 EST


Convert etnaviv bindings to yaml format.
Move bindings file from display to gpu folder.

version 3:
- describe clock-names as enum to allow all possible mix

version 2:
- move bindings file from display to gpu folder

-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>;
-};
