+Device-Tree bindings for Ingenic JZ4780 HDMI Transmitter
+
+The HDMI Transmitter in the Ingenic JZ4780 is a Synopsys DesignWare HDMI 1.4
+TX controller IP with accompanying PHY IP.
+
+Required properties:
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+ - compatible : should be "ingenic,jz4780-hdmi"
+ - reg-io-width: must be <4>
+ - clocks: phandle to isrf and iahb clocks
+ - clock-names : must be "isrf" and "iahb"
+ - ports: Port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt,
+
+Optional properties:
+ - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+
+example:
+
+hdmi: hdmi@10180000 {
+ compatible = "ingenic,jz4780-hdmi";
+ reg = <0x10180000 0x8000>;
+ reg-io-width = <4>;
+ ddc-i2c-bus = <&i2c4>;
+ interrupt-parent = <&intc>;
+ interrupts = <3>;
+ clocks = <&cgu JZ4780_CLK_HDMI>, <&cgu JZ4780_CLK_AHB0>;
+ clock-names = "isfr", "iahb";
+
+ ports {
+ hdmi_in: port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ hdmi_in_lcd: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&jz4780_out_hdmi>;
+ };
+ };
+ };
+};
