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!
