+ This enables printing of debug messages. Alternatively, debug messages

+ default 0
+ help
+ This can be used to adjust the minimum FCK/PCK ratio.
+
+ With this you can make sure that DISPC FCK is at least
+ n x PCK. Video plane scaling requires higher FCK than
+ normally.
+
+ If this is set to 0, there's no extra constraint on the
+ DISPC FCK. However, the FCK will at minimum be
+ 2xPCK (if active matrix) or 3xPCK (if passive matrix).
+
+ Max FCK is 173MHz, so this doesn't work if your PCK
+ is very high.
+
+config OMAP2_DSS_SLEEP_AFTER_VENC_RESET
+ bool "Sleep 20ms after VENC reset"
+ default y
+ help
+ There is a 20ms sleep after VENC reset which seemed to fix the
+ reset. The reason for the bug is unclear, and it's also unclear
+ on what platforms this happens.
+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.
