Subject: [PATCH 1070/1085] drm/panel-simple: Increase pixel clock on Pi 7inch
|
|
panel
|
|
|
|
The Toshiba bridge is very fussy and doesn't like the CM3
|
|
output when being told to produce a 27.777MHz pixel clock, which
|
|
is an almost perfect match to the DSI link integer divider.
|
|
|
|
Increasing to 30MHz will switch the DSI link from 333MHz to 400MHz
|
|
and makes the bridge happy with the same video timing as works
|
|
on Pi4.
|
|
(Pi4 will be using a link frequency of 375MHz due to a 3GHz
|
|
parent PLL).
