+Allwinner HDMI Transmitter
+==========================
+
+The Allwinner HDMI transmitters are included in the SoCs.
+They support audio and video.
+
+Required properties:
+ - compatible : should be one of
+ "allwinner,sun8i-a83t-hdmi"
+ "allwinner,sun8i-h3-hdmi"
+ - reg: base address and size of the I/O memory
+ - clocks : phandles to the HDMI clocks as described in
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ - clock-names : must be
+ "bus" : bus gate
+ "clock" : streaming clock
+ "ddc-clock" : DDC clock
+ - resets : One or two phandles to the HDMI resets
+ - reset-names : when 2 phandles, must be
+ "hdmi0" and "hdmi1"
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+
+Required nodes:
+ - port: Audio and video input port nodes with endpoint definitions
+ as defined in Documentation/devicetree/bindings/graph.txt.
+ port@0 is video and port@1 is audio.
+
+Example:
+
+ hdmi: hdmi@01ee0000 {
+ compatible = "allwinner,sun8i-a83t-hdmi";
+ reg = <0x01ee0000 0x20000>;
+ clocks = <&ccu CLK_BUS_HDMI>, <&ccu CLK_HDMI>,
+ <&ccu CLK_HDMI_DDC>;
+ clock-names = "bus", "clock", "ddc-clock";
+ resets = <&ccu RST_HDMI0>, <&ccu RST_HDMI1>;
+ reset-names = "hdmi0", "hdmi1";
+ pinctrl-names = "default";
+ pinctrl-0 = <&hdmi_pins_a>;
+ status = "disabled";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ port@0 { /* video */
+ reg = <0>;
+ hdmi_tcon1: endpoint {
+ remote-endpoint = <&tcon1_hdmi>;
+ };
+ };
+ port@1 { /* audio */
+ reg = <1>;
+ hdmi_i2s2: endpoint {
+ remote-endpoint = <&i2s2_hdmi>;
+ };
+ };
+ };
