Merge branch 'drm-lcdc' of git://linuxtv.org/pinchartl/fbdev into drm-next 

Laurent writes:

The SH Mobile DRM driver is now (in my opinion) ready for mainline. It
requires GEM and KMS/FB helpers that have been reviewed on the list and
tested. Sascha is waiting for them to reach your tree to send a pull request
for another new driver.

* 'drm-lcdc' of git://linuxtv.org/pinchartl/fbdev:
  drm: Renesas SH Mobile DRM driver
  drm: Add NV24 and NV42 pixel formats
  DRM: Add DRM KMS/FB CMA helper
  DRM: Add DRM GEM CMA helper
  drm/edid: limit printk when facing bad edid
