   4 Subject: [PATCH 0636/1085] drm/panel: simple: Alter the timing for the Pi 7"
   5  DSI display
   6
   7 vc4 has always fixed up the timing, so the values defined have
   8 never actually appeared on the wire.
   9 The display appears to want a slightly longer HFP, so extend
  10 the timings and recompute the clock to give the same frame rate.
