  14           can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting

  88           processor and a peripheral, such as a display or a framebuffer chip.

  97           This can be used to adjust the minimum FCK/PCK ratio.
  98
  99           With this you can make sure that DISPC FCK is at least
 100           n x PCK. Video plane scaling requires higher FCK than
 101           normally.
 102
 103           If this is set to 0, there's no extra constraint on the
 104           DISPC FCK. However, the FCK will at minimum be
 105           2xPCK (if active matrix) or 3xPCK (if passive matrix).
 106
 107           Max FCK is 173MHz, so this doesn't work if your PCK
 108           is very high.

 114           There is a 20ms sleep after VENC reset which seemed to fix the
 115           reset. The reason for the bug is unclear, and it's also unclear
 116           on what platforms this happens.
 117
 118           This option enables the sleep, and is enabled by default. You can
 119           disable the sleep if it doesn't cause problems on your platform.
