Feature regression is something that shouldn't happen. If we add the driver
with a color conversion inside, we should somehow keep this feature available
on newer versions. That's said, I don't see any issue if the later versions do
this implementation inside hardware/firmware, since the end result is that the
driver will keep supporting those standards.

From my side, I'm ok on having this color conversion for a short timeframe (one
or two kernel releases), if you are sure that those features will be present
on the next firmwares.

The better is to mark the driver as EXPERIMENTAL, at Kconfig.
