 111          This can be used to adjust the minimum FCK/PCK ratio.
 112
 113          With this you can make sure that DISPC FCK is at least
 114          n x PCK. Video plane scaling requires higher FCK than
 115          normally.
 116
 117          If this is set to 0, there's no extra constraint on the
 118          DISPC FCK. However, the FCK will at minimum be
 119          2xPCK (if active matrix) or 3xPCK (if passive matrix).
 120
 121          Max FCK is 173MHz, so this doesn't work if your PCK
 122          is very high.

 128          There is a 20ms sleep after VENC reset which seemed to fix the
 129          reset. The reason for the bug is unclear, and it's also unclear
 130          on what platforms this happens.
 131
 132          This option enables the sleep, and is enabled by default. You can
 133          disable the sleep if it doesn't cause problems on your platform.
