[PATCH 0/8] tilcdc-panel: Backlight and GPIO devicetree support

[Ezequiel Garcia]

Hello all,

This patchset adds the required changes to support an optional backlight
and GPIO for the tilcdc panel driver.

There was some code to support a backlight, but it was somewhat broken
and undocumented. I've followed the nice implementation in panel-simple
and added a similar one here.

The enable GPIO is required to turn on and off devices with such capability.
Also here, I've followed panel-simple which looks correct.

In addition to this there are very minor cosmetic cleanups and a larger
error path fix in tilcdc's DRM driver .load error path.

This patchset applies on top of drm-next branch which contains the latest
tilcdc pushed by Guido.

If at all possible, I'd like to get this merged for v3.17. If a pull request
is needed, don't hesitate to ask and I'll prepare one.

Comments and tests welcome!
