  83. This can be used to adjust the minimum FCK/PCK ratio.
  84. With this you can make sure that DISPC FCK is at least
  85. n x PCK. Video plane scaling requires higher FCK than
  86. normally.
  87. If this is set to 0, there's no extra constraint on the
  88. DISPC FCK. However, the FCK will at minimum be
  89. 2xPCK (if active matrix) or 3xPCK (if passive matrix).
  90. Max FCK is 173MHz, so this doesn't work if your PCK
  91. is very high.

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