[PATCH v2 00/19] drm: rcar-du: Add Color Management Module (CMM)

[Jacopo Mondi]

Hello,
  second iteration of CMM support for Renesas R-Car devices, where I have
fixed comments from Laurent, Geert and Daniel.

A reference to the v1 cover letter, with some background on the CMM is
available here:
https://lkml.org/lkml/2019/6/6/583

Notable changes:
- Rebased on v5.2-rc7
- clock patches rebased, but already collected by Geert for v5.3
- Changed cmm compatible string as suggested by Geert in bindings and
  DTS files
- CMM driver updated to include comments from Laurent, thanks!
- Integration in R-Car DU is very similar, I have squashed a few patches
- Add legagy gamma interface support with .gamma_set callback as suggested
  by Daniel.

Thanks
