 107           This can be used to adjust the minimum FCK/PCK ratio.
 108
 109           With this you can make sure that DISPC FCK is at least
 110           n x PCK. Video plane scaling requires higher FCK than
 111           normally.
 112
 113           If this is set to 0, there's no extra constraint on the
 114           DISPC FCK. However, the FCK will at minimum be
 115           2xPCK (if active matrix) or 3xPCK (if passive matrix).
 116
 117           Max FCK is 173MHz, so this doesn't work if your PCK
 118           is very high.
