 118           This can be used to adjust the minimum FCK/PCK ratio.
 119
 120           With this you can make sure that DISPC FCK is at least
 121           n x PCK. Video plane scaling requires higher FCK than
 122           normally.
 123
 124           If this is set to 0, there's no extra constraint on the
 125           DISPC FCK. However, the FCK will at minimum be
 126           2xPCK (if active matrix) or 3xPCK (if passive matrix).

 128           Max FCK is 173MHz, so this doesn't work if your PCK
 129           is very high.

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

 137           on what platforms this happens.
 138
 139           This option enables the sleep, and is enabled by default. You can
 140           disable the sleep if it doesn't cause problems on your platform.
