18	help
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!)).
23
24	  To have support for your specific LCD panel you will have to
25	  select the proper drivers which depend on this option.

31	help
32	  If you have a Samsung LTV350QV LCD panel, say y to include a
33	  power control driver for it.  The panel starts up in power
34	  off state, so you need this driver in order to see any
35	  output.

48          backlight. This includes support for brightness and power.

56	default y if MACH_SAM9261EK || MACH_SAM9263EK
57	help
58	  This provides a backlight control internal to the Atmel LCDC
59	  driver.  If the LCD "contrast control" on your board is wired
60	  so it controls the backlight brightness, select this option to
61	  export this as a PWM-based backlight control.
62
63	  If in doubt, it's safe to enable this option; it doesn't kick
64	  in unless the board's description says it's wired that way.
