This "panel" is actually an RGB panel with a MIPI-DSI-to-RGB bridge
tacked on. On one particular revision of this module, one can also
directly use the RGB interface.

Would it be better to model this as bridge+panel? We already have
a binding for the RGB version [1]. This would make it harder to
make a driver though, as there is no publicly available datasheet
for the bridge chip, so it's likely that part of the init sequence
would have to be hard-coded.

Thanks
