+DesignWare HDMI bridge bindings
+
+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"
+
+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"
+
+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>;
+ };
+ };
+ };
