First of all, please split changes to DT, to the clock drivers, to the
dw-hdmi driver, to the DRM core and to the R-Car DU driver in separate
patches, with appropriate subject lines prefixes for each of them. As
you're modifying DT bindngs, you also need to update the bindings
documentation, which should go to a patch of its own.
