This binding is mostly a copy of the existing Documentation/devicetree/bindings/drm/imx/hdmi.txt, but there is a new reg-io-width property to configure the register access bus width and we have added new compatibles "rockchip,rk3288-dw-hdmi" and the common "snps,dw-hdmi-tx". Could we get an Ack for this and patch 11 by the device tree maintainers?
regards Philipp

+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 {
