s/compatibel/compatible/
This should include the _precise_ strings you expect. Please format this
as a list, e.g.
- compatible: should contain one of:
* "fsl,imx6q-hdmi"
* "fsl,imx6dl-hdmi"
* "rockchip,rk3288-dw-hdmi"

Does the device only have one interrupt? Just describe what this
logically is, and don't mention the CPU. It'll be plumbed through an
interrupt controller anyhow.

I don't understand this description. Could you elaborate on this?

These three properties weren't mentioned in the binding.

Please mention the graphics bindings that require graph info.
THanks,
