The series adds plane specific atomic properties to control YCbCr to

I would probably extend this series to have a bigger view. Instead of
addressing RGB->YCBCR conversion, the actual target here should be
blending of various framebuffers considering:
- their color spaces (Rec 601/709/2020)
- their format (YCBCR->RGB or RGB->YCBCR)
- their linear state (Linear/Non-linear) or if they are ready for Gamut
mapping/color conversion or not.
Also, we need to have the sequence of properties, so that, it would
match all(most of the) HWs.
I will add my comments in the upcoming patches accordingly.

This series may not be ready as such. At least the kernel doc parts
should be more detailed and carefully written. The purpose is merely
to move the discussion to a more concrete level.
The series also includes drm/omap patches that implement the standard
properties for OMAP DSS in omapdrm driver.
Best regards,
