1 DesignWare HDMI bridge bindings
3 Required properties:
4 - compatible: platform specific such as:
5    * "snps,dw-hdmi-tx"
6    * "fsl,imx6q-hdmi"
7    * "fsl,imx6dl-hdmi"
8    * "rockchip,rk3288-dw-hdmi"
9 - reg: Physical base address and length of the controller's registers.
10 - interrupts: The HDMI interrupt number
11 - clocks, clock-names : must have the phandles to the HDMI iahb and isfr clocks,
12   as described in Documentation/devicetree/bindings/clock/clock-bindings.txt,
13   the clocks are soc specific, the clock-names should be "iahb", "isfr"
14 -port@[X]: SoC specific port nodes with endpoint definitions as defined
15    in Documentation/devicetree/bindings/media/video-interfaces.txt,
16    please refer to the SoC specific binding document:
17     * Documentation/devicetree/bindings/drm/imx/hdmi.txt
18     * Documentation/devicetree/bindings/video/dw_hdmi-rockchip.txt
20 Optional properties
21 - reg-io-width: the width of the reg:1,4, default set to 1 if not present
22 - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
23 - clocks, clock-names: phandle to the HDMI CEC clock, name should be "cec"
