[PATCH 00/10] drm/panel: Remove unnecessary enabled/prepared state

[Sean Paul]

A number of panel drivers track enabled/prepared state (I suspect to protect
regulator refcounts). However, the atomic framework already ensures that
prepare/unprepare and enable/disable calls are balanced. This series removes all
independent tracking from the drivers and adds a WARNING to the core in case
someone uses a panel with a legacy driver.


Sean Paul (10):
  drm/panel: Keep track of enabled/prepared
