[PATCH] drm/panel-simple: Add a timing for the Raspberry Pi 7" panel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

The Raspberry Pi 7" 800x480 panel uses a Toshiba TC358762 DSI
to DPI bridge chip, so there is a requirement for the timings
to be specified for the end panel. Add such a definition.
