MIPI DSI (Display Serial Interface) support.

default 0
|
help
|
This can be used to adjust the minimum FCK/PCK ratio.
|
|
With this you can make sure that DISPC FCK is at least
|
n x PCK. Video plane scaling requires higher FCK than
|
normally.
|
|
If this is set to 0, there's no extra constraint on the
|
DISPC FCK. However, the FCK will at minimum be
|
2xPCK (if active matrix) or 3xPCK (if passive matrix).
|
|
Max FCK is 173MHz, so this doesn't work if your PCK
|
is very high.

There is a 20ms sleep after VENC reset which seemed to fix the

reset. The reason for the bug is unclear, and it's also unclear
|
on what platforms this happens.
|
|
This option enables the sleep, and is enabled by default. You can
|
disable the sleep if it doesn't cause problems on your platform.
