  12. The amount of SDRAM to reserve at boot time for video RAM use.
  13. This VRAM will be used by omapfb and other drivers that need
  14. large continuous RAM area for video use.
  15. You can also set this with "vram=<bytes>" kernel argument, or
  16. in the board file.

  29. The statistics can be found from

  36. MIPI DBI support (RFBI, Remote Framebuffer Interface, in Texas
  37. Instrument's terminology).
  38. DBI is a bus between the host processor and a peripheral,
  39. such as a display or a framebuffer chip.
  40. See http://www.mipi.org/ for DBI spesifications.

  74. If this is selected, DSI will generate a fake DISPC VSYNC interrupt
  75. when DSI has sent a frame. This is only needed with DSI or RFBI
  76. displays using manual mode, and you want VSYNC to, for example,
  77. time animation.

  82. help
  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.
