  79. This can be used to adjust the minimum FCK/PCK ratio.
  80. With this you can make sure that DISPC FCK is at least
  81. n x PCK. Video plane scaling requires higher FCK than
  82. normally.
  83. If this is set to 0, there's no extra constraint on the
  84. DISPC FCK. However, the FCK will at minimum be
  85. 2xPCK (if active matrix) or 3xPCK (if passive matrix).
  86. Max FCK is 173MHz, so this doesn't work if your PCK
  87. is very high.

  92. There is a 20ms sleep after VENC reset which seemed to fix the
  93. reset. The reason for the bug is unclear, and it's also unclear
  94. on what platforms this happens.
  95. This option enables the sleep, and is enabled by default. You can
  96. disable the sleep if it doesn't cause problems on your platform.
