Nice work.

This patch should move the binding from

Documentation/devicetree/bindings/staging/imx-drm/hdmi.txt
to the location instead of making a new file and leaving the old
one in place.

And use git format-patch -M to highlight any changes.

I add these bindings for dw-hdmi core, because
properities like reg, interrupts, ddc-i2c-bus, reg-io-width are used
by dw-hdmi core, but properities like compatible, gpr,clk, are platform
specific , they are handled by the platform code like dw_hdmi-imx.c
and described in platform specific dt binds like /imx-drm/hdmi.txt

+DesignWare HDMI bridge bindings
+
+Required properities:
+- compatibel: platform specific such as "fsl,imx6q-hdmi","fsl,imx6dl-hdmi"
+ "rockchip,rk3288-dw-hdmi"
+- reg: physical base address of the controller and length
+- ddc-i2c-bus: the ddc i2c bus
+- interrupts: The interrupt number to the cpu
+
+Optional properties
+- reg-io-width: the width of the reg:1,4, default set to 1 if not present
+
+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>;
+ };
+ };
+ };
