[PATCH 2/5] panel-simple: Add the 7" DPI panel from Adafruit.

[Eric Anholt]

This is a basic TFT panel with a 40-pin FPC connector on it.  The
specification doesn't define timings, but the Adafruit instructions
were setting up 800x480 CVT.

v2: Add .bus_format and vsync/hsync flags.

[PATCH 2/5] panel-simple: Add the 7" DPI panel from Adafruit.

[Eric Anholt]

This is a basic TFT panel with a 40-pin FPC connector on it.  The
specification doesn't define timings, but the Adafruit instructions
were setting up 800x480 CVT.
