   6           Turn on this option to enable a very simple driver which uses vesa
   7           to discover the video mode and then provides a frame buffer for use
   8           by U-Boot.

  12         default n
  13         ---help---
  14         Support for the SSD2828 bridge chip, which can take pixel data coming
  15         from a parallel LCD interface and translate it on the fly into MIPI DSI
  16         interface for driving a MIPI compatible LCD panel. It uses SPI for
  17         configuration.

  22         default 0
  23         ---help---
  24         The frequency of the crystal, which is clocking SSD2828. It may be
  25         anything in the 8MHz-30MHz range and the exact value should be
  26         retrieved from the board schematics. Or in the case of Allwinner
  27         hardware, it can be usually found as 'lcd_xtal_freq' variable in
  28         FEX files. It can be also set to 0 for selecting PCLK from the
  29         parallel LCD interface instead of TX_CLK as the PLL clock source.

  34         default ""
  35         ---help---
  36         The reset pin of SSD2828 chip. This takes a string in the format
  37         understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.

  44         Support for Hitachi tx18d42vm LVDS LCD panels, these panels have a
  45         lcd controller which needs to be initialized over SPI, once that is
  46         done they work like a regular LVDS panel.

  82         ---help---
  83         This is one of the SPI communication pins, involved in setting up a
  84         working LCD configuration. The exact role of SPI may differ for
  85         different hardware setups. If wired up, this pin may provide additional
  86         useful functionality. Such as bi-directional communication with the
  87         hardware and LCD panel id retrieval (if the panel can report it). The
  88         option takes a string in the format understood by 'name_to_gpio'
  89         function, e.g. PH1 for pin 1 of port H.
