   4 Subject: [PATCH] drm/panel: simple: Add the 7" DPI panel from Adafruit
   5
   6 This is a basic TFT panel with a 40-pin FPC connector on it.  The
   7 specification doesn't define timings, but the Adafruit instructions
   8 were setting up 800x480 CVT.
   9
  10 v2: Add .bus_format and vsync/hsync flags.
