14	  The amount of SDRAM to reserve at boot time for video RAM use.
15	  This VRAM will be used by omapfb and other drivers that need

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

124	  There is a 20ms sleep after VENC reset which seemed to fix the
125	  reset. The reason for the bug is unclear, and it's also unclear
126	  on what platforms this happens.
