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