Hm, this kinda contradicts your chngnelog, no?

I'm getting the following on the SILK board with this patch:

[drm] Initialized drm 1.1.0 20060810
sh-pfc e6060000.pin-controller: does not have pin group du1_dotclkout0
sh-pfc e6060000.pin-controller: invalid group du1_dotclkout0 in map table
[drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[drm] No driver support for vblank timestamp query.
rcar-du feb00000.display: fb0: frame buffer device
[drm] Initialized rcar-du 1.0.0 20130110 on minor 0

MBR, Sergei
