  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.

  21. This enables debug messages. You need to enable printing
  22. with 'debug' module parameter.

  50. Use DSI PLL to generate pixel clock. Currently only for DPI output.
  51. DSI PLL can be used to generate higher and more precise pixel clocks.

  55. help
  56. If this is selected, DSI will generate a fake DISPC VSYNC interrupt
  57. when DSI has sent a frame. This is only needed with DSI or RFBI
  58. displays using manual mode, and you want VSYNC to, for example,
  59. time animation.
  60. config OMAP2_DSS_MIN_FCK_PER_PCK

  63. default 0
  64. help
  65. This can be used to adjust the minimum FCK/PCK ratio.
  66. With this you can make sure that DISPC FCK is at least
  67. n x PCK. Video plane scaling requires higher FCK than
  68. normally.
  69. If this is set to 0, there's no extra constraint on the
  70. DISPC FCK. However, the FCK will at minimum be
  71. 2xPCK (if active matrix) or 3xPCK (if passive matrix).
  72. Max FCK is 173MHz, so this doesn't work if your PCK
  73. is very high.
