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

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

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

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