116 help
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).
126
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
135 reset. The reason for the bug is unclear, and it's also unclear
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.
