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 j
