Hi Laurent-san
I am Hiep from Jinzai Solution.

We have tested the linux ver 3.19 on Koelsch, we found some error 
messages from Rcar-Du as show below:
The error messages:
"[drm] Initialized drm 1.1.0 20060810
  rcar-du feb00000.display: Failed to initialize drm fb helper.
  rcar-du feb00000.display: failed to initialize DRM/KMS
  rcar-du: probe of feb00000.display failed with error -22"

Then, we find out these patches as below are causing of this bug:
0ee56d4 ARM: shmobile: koelsch: Enable DU device in DT
910343e ARM: shmobile: koelsch-reference: Remove DU platform device

Please see them when you have time!

Best Regards,
Jinso/Cao Minh Hiep.
