  19           This framework adds support for low-level control of LCD.
  20           Some framebuffer devices connect to platform-specific LCD modules
  21           in order to have a platform-specific way to control the flat panel
  22           (contrast and applying power to the LCD (not to the backlight!)).

  24           To have support for your specific LCD panel you will have to

 115           This provides a backlight control internal to the Atmel LCDC
 116           driver.  If the LCD "contrast control" on your board is wired

 118           export this as a PWM-based backlight control.
 119
 120           If in doubt, it's safe to enable this option; it doesn't kick
 121           in unless the board's description says it's wired that way.
