Subject: [PATCH 680/828] drm/vc4: dsi: Correct max divider to 255 (not 7)
|
|
|
|
The integer divider from parent PLL to DSI clock is capable
|
|
of going up to /255, not just /7 that the driver was trying.
|
|
This allows for slower link frequencies on the DSI bus where
|
|
the resolution permits.
