[Intel-gfx] [PATCH 2/5] drm/i915: PCH_ prefix for transcoder timings
Daniel Vetter
daniel.vetter at ffwll.ch
Wed May 1 18:03:14 CEST 2013
While at it, also extract a common helper to copy the timings from the
cpu transcoder to the pch transcoder. That way it's really explicit
how the lpt transcoder is hardcoded.
