Dave,
I'm resending this, hoping it can be pushed for v3.18. The patchset was ready for v3.17, but it got no maintainer feedback or review. Maybe it fell through some crack?
Just for reference, here goes the details about this series and why it's needed:
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 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 fix for the error path in tilcdc's DRM driver .load error path.
