92 range 0 32
93 default 0
94 help
95 This can be used to adjust the minimum FCK/PCK ratio.
96
97 With this you can make sure that DISPC FCK is at least
98 n x PCK. Video plane scaling requires higher FCK than
99 normally.
100
101 If this is set to 0, there's no extra constraint on the
102 DISPC FCK. However, the FCK will at minimum be
103 2xPCK (if active matrix) or 3xPCK (if passive matrix).
104
105 Max FCK is 173MHz, so this doesn't work if your PCK
106 is very high.

110 default y
111 help
112 There is a 20ms sleep after VENC reset which seemed to fix the
113 reset. The reason for the bug is unclear, and it's also unclear
114 on what platforms this happens.
115
116 This option enables the sleep, and is enabled by default. You can
117 disable the sleep if it doesn't cause problems on your platform.
