17	default m
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.

27config LCD_CORGI
28	tristate "LCD Panel support for SHARP corgi/spitz model"
29	depends on LCD_CLASS_DEVICE && SPI_MASTER && PXA_SHARPSL

35	tristate "Samsung LTV350QV LCD Panel"
36	depends on LCD_CLASS_DEVICE && SPI_MASTER
37	default n
38	help
39	  If you have a Samsung LTV350QV LCD panel, say y to include a
40	  power control driver for it.  The panel starts up in power
41	  off state, so you need this driver in order to see any
42	  output.
43
44	  The LTV350QV panel is present on all ATSTK1000 boards.

84	default m
85	help
86	  This framework adds support for low-level control of the LCD
87          backlight. This includes support for brightness and power.
88
89	  To have support for your specific LCD panel you will have to
90	  select the proper drivers which depend on this option.

94	depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
95	default y if MACH_SAM9261EK || MACH_SAM9263EK
96	help
97	  This provides a backlight control internal to the Atmel LCDC
98	  driver.  If the LCD "contrast control" on your board is wired
99	  so it controls the backlight brightness, select this option to
100	  export this as a PWM-based backlight control.
101
102	  If in doubt, it's safe to enable this option; it doesn't kick
103	  in unless the board's description says it's wired that way.

105config BACKLIGHT_ATMEL_PWM
106	tristate "Atmel PWM backlight control"
107	depends on BACKLIGHT_CLASS_DEVICE && ATMEL_PWM
108	default n
109	help
110	  Say Y here if you want to use the PWM peripheral in Atmel AT91 and
111	  AVR32 devices. This driver will need additional platform data to know
112	  which PWM instance to use and how to configure it.
113
114	  To compile this driver as a module, choose M here: the module will be
115	  called atmel-pwm-bl.

122	  Say y to enable the generic platform backlight driver previously
123	  known as the Corgi backlight driver. If you have a Sharp Zaurus
124	  SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
