  94. This can be used to adjust the minimum FCK/PCK ratio.
  95. With this you can make sure that DISPC FCK is at least
  96. n x PCK. Video plane scaling requires higher FCK than
  97. normally.
  98. If this is set to 0, there's no extra constraint on the
  99. DISPC FCK. However, the FCK will at minimum be
  100. 2xPCK (if active matrix) or 3xPCK (if passive matrix).

  109. on what platforms this happens.

  111. disable the sleep if it doesn't cause problems on your platform.
