+Required properities: +- compatible: platform specific such as:
- "snps,dw-hdmi-tx"
- "fsl,imx6q-hdmi"
- "fsl,imx6dl-hdmi"
- "rockchip,rk3288-dw-hdmi"
+- reg: Physical base address and length of the controller's registers. +- interrupts: The HDMI interrupt number +- clocks, clock-names : must have the phandles to the HDMI iahb and isrf clocks,
- as described in Documentation/devicetree/bindings/clock/clock-bindings.txt,
- the clock-names should be "iahb", "isfr"
This is missing the port bindings, I think it should mention the port property here and refer to the soc specific binding document.
- port@...: SoC specific port nodes with endpoint definitions as defined in Documentation/devicetree/bindings/media/video-interfaces.txt, please refer to the SoC specific binding document: * Documentation/devicetree/bindings/drm/imx/hdmi.txt * Documentation/devicetree/bindings/video/dw_hdmi-rockchip.txt
This also makes be wonder, shouldn't dw_hdmi-rockchip be under drm/?
+Optional properties +- reg-io-width: the width of the reg:1,4, default set to 1 if not present +- ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing +- clkocks, clock-names: phandle to the HDMI cec clock, name should be "cec"
s/clkocks/clocks/, and I'd uppercase the HDMI CEC clock for consistency.
+Example:
- hdmi: hdmi@0120000 {
compatible = "fsl,imx6q-hdmi";
Could you change this example to: compatible = "fsl,imx6q-hdmi", "snps,dw-hdmi-tx"
reg = <0x00120000 0x9000>;
interrupts = <0 115 0x04>;
gpr = <&gpr>;
clocks = <&clks 123>, <&clks 124>;
clock-names = "iahb", "isfr";
ddc-i2c-bus = <&i2c2>;
port@0 {
reg = <0>;
hdmi_mux_0: endpoint {
remote-endpoint = <&ipu1_di0_hdmi>;
};
};
port@1 {
reg = <1>;
hdmi_mux_1: endpoint {
remote-endpoint = <&ipu1_di1_hdmi>;
};
};
- };
