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

  106. on what platforms this happens.
  107. This option enables the sleep, and is enabled by default. You can
  108. disable the sleep if it doesn't cause problems on your platform.
