Hi Jitao.

A few comments that I missed in last round.

Please consider to combine the three panels in one binding.
I realise they are almost identical so no need for three binding files.

Please use (GPL-2.0-only OR BSD-2-Clause) for all new bindings.
(Sorry if this was not part of my previous feedback)

Rob is not a typical maintainer of panel bindings.
The fallback it Thierry and me.

But if you have agreed this with Rob then all is good.

I would be suprised if backlight is a required node.
You could always tie the input to a fixed voltage and then no backlight
node are required.
Please remove from the required list unless you can convince me
otherwise.
