   5  properties

  10 Commit 731514b446fe6748d5a55a3dff202efb45c7d8df upstream.
  11 Reworked as functions have been moved from drm_atomic_helper.[c|h]
  12 to drm_atomic_state_helper.[c|h].
  13
  14 During the connector reset, if that connector has a TV property, it needs
  15 to be reset to the value provided on the command line.
  16
  17 Provide a helper to do that.
