[PATCH V2 0/3] drm/bridge: it66121: Add it66122 support

From: Nishanth Menon

Hi,

Add support for IT66122, which for all practical purposes is
drop in replacement for IT66121 except for the ID register
definition.

BeagleY-AI uses this new part as the old part is no longer in production
as far as I understand.

Now, BeaglePlay uses it66121 at the moment, but at some point, it might
end up flipping over to the new part.

Quick boot log on BeaglePlay for compatibility check:

Changes since V1:
* Picked up Krystoff's binding ack
* Switched over to a vid/pid list

V1: https://lore.kernel.org/all/20250813190835.344563-1-nm@xxxxxx/
