- Subject: [PATCH 341/381] 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.
- Signed-off-by: Eric Anholt <eric@anholt.net>
- Acked-by: Rob Herring <robh@kernel.org>
- [treding@nvidia.com: keep entries properly sorted]
- Signed-off-by: Thierry Reding <treding@nvidia.com>
- (cherry picked from commit 8070fdbd024727c752f815b18e5339c681a01bbe)
