DesignWare HDMI bridge bindings
|
|
|
|
Required properties:
|
|
- 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 isfr clocks,
|
|
as described in Documentation/devicetree/bindings/clock/clock-bindings.txt,
|
|
the clocks are soc specific, the clock-names should be "iahb", "isfr"
|
|
-port@[X]: 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
|
|
|
|
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
|
|
- clocks, clock-names: phandle to the HDMI CEC clock, name should be "cec"
|
|
|
|
Example:
|
|
hdmi: hdmi@0120000 {
|
|
compatible = "fsl,imx6q-hdmi";
|
|
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>;
|
|
};
|
|
};
|
|
};
