CONFIG_OMAP2_DSS_SLEEP_BEFORE_RESET is used to avoid an unclear bug at DSS reset time. The pm runtime will handle reset in the future, and this code has to be removed. Hopefully we won't see this error anymore. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

If this is selected, DSI will generate a fake DISPC VSYNC interrupt

|
|
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.
