+Subject: [PATCH 338/423] 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.

+(cherry picked from commit 8070fdbd024727c752f815b18e5339c681a01bbe)
