Subject: [PATCH] drm/panel: simple: Add the 7" DPI panel from Adafruit
|
|
|
|
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.
