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

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