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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Ezequiel Garcia (8):
  drm/tilcdc: Fix the error path in tilcdc_load()
  drm/tilcdc: panel: Add missing of_node_put
  drm/tilcdc: panel: Remove unused variable
  drm/tilcdc: panel: Spurious whitespace removal
  drm/tilcdc: panel: Use devm_kzalloc to simplify the error path
  drm/tilcdc: panel: Fix backlight devicetree support
  drm/tilcdc: panel: Set return value explicitly
  drm/tilcdc: panel: Add support for enable GPIO
