  10. This enables printing of debug messages. Alternatively, debug messages
  11. can also be enabled by setting CONFIG_DYNAMIC_DEBUG and then setting
  12. appropriate flags in <debugfs>/dynamic_debug/control.

  18. This enables debugfs for OMAPDSS at <debugfs>/omapdss. This enables
  19. querying about clock configuration and register configuration of dss,

  39. MIPI DBI support (RFBI, Remote Framebuffer Interface, in Texas
  40. Instrument's terminology).
  41. DBI is a bus between the host processor and a peripheral,
  42. such as a display or a framebuffer chip.

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

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