ChangeLog v9->v11:
- Now uses the drm-panel instead of the display-timings.

ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- The backlight is now on at boot.

ChangeLog v6->v7:
- Shrinked even more the Cc list.

ChangeLog v5->v6:
- Reordered the Cc list.

ChangeLog v3->v5:
- Updated to the new GPIO defines.

ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51 boards.
- This patch now only adds backlight support.
- Added some interested people in the Cc list, and removed some people that
  might be annoyed by the receiving of that patch which is unrelated to their
  subsystem.
