This enables printing of debug messages. Alternatively, debug messages
can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting
appropriate flags in <debugfs>/dynamic_debug/control.

This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables
querying about clock configuration and register configuration of dss,
dispc, dsi, hdmi and rfbi.

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.
