2 # Backlight & LCD drivers configuration
5 menuconfig BACKLIGHT_LCD_SUPPORT
6 bool "Backlight & LCD device support"
8 Enable this to be able to choose the drivers for controlling the
9 backlight and the LCD panel on some platforms, for example on PDAs.
14 config LCD_CLASS_DEVICE
15 tristate "Lowlevel LCD controls"
16 depends on BACKLIGHT_LCD_SUPPORT
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
25 select the proper drivers which depend on this option.
28 tristate "Samsung LTV350QV LCD Panel"
29 depends on LCD_CLASS_DEVICE && SPI_MASTER
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
37 The LTV350QV panel is present on all ATSTK1000 boards.
41 depends on LCD_CLASS_DEVICE && BACKLIGHT_LCD_SUPPORT
44 If you have a panel based on the ILI9320 controller chip
45 then say y to include a power driver for it.
48 tristate "VGG2432A4 LCM device support"
49 depends on BACKLIGHT_LCD_SUPPORT && LCD_CLASS_DEVICE && SPI_MASTER
53 If you have a VGG2432A4 panel based on the ILI9320 controller chip
54 then say y to include a power driver for it.
57 tristate "Platform LCD controls"
58 depends on LCD_CLASS_DEVICE
60 This driver provides a platform-device registered LCD power
66 config BACKLIGHT_CLASS_DEVICE
67 tristate "Lowlevel Backlight controls"
68 depends on BACKLIGHT_LCD_SUPPORT
71 This framework adds support for low-level control of the LCD
72 backlight. This includes support for brightness and power.
74 To have support for your specific LCD panel you will have to
75 select the proper drivers which depend on this option.
77 config BACKLIGHT_ATMEL_LCDC
78 bool "Atmel LCDC Contrast-as-Backlight control"
79 depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
80 default y if MACH_SAM9261EK || MACH_SAM9263EK
82 This provides a backlight control internal to the Atmel LCDC
83 driver. If the LCD "contrast control" on your board is wired
84 so it controls the backlight brightness, select this option to
85 export this as a PWM-based backlight control.
87 If in doubt, it's safe to enable this option; it doesn't kick
88 in unless the board's description says it's wired that way.
90 config BACKLIGHT_ATMEL_PWM
91 tristate "Atmel PWM backlight control"
92 depends on BACKLIGHT_CLASS_DEVICE && ATMEL_PWM
95 Say Y here if you want to use the PWM peripheral in Atmel AT91 and
96 AVR32 devices. This driver will need additional platform data to know
97 which PWM instance to use and how to configure it.
99 To compile this driver as a module, choose M here: the module will be
102 config BACKLIGHT_CORGI
103 tristate "Generic (aka Sharp Corgi) Backlight Driver"
104 depends on BACKLIGHT_CLASS_DEVICE
107 Say y to enable the generic platform backlight driver previously
108 known as the Corgi backlight driver. If you have a Sharp Zaurus
109 SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
111 config BACKLIGHT_LOCOMO
112 tristate "Sharp LOCOMO LCD/Backlight Driver"
113 depends on BACKLIGHT_CLASS_DEVICE && SHARP_LOCOMO
116 If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
117 enable the LCD/backlight driver.
119 config BACKLIGHT_OMAP1
120 tristate "OMAP1 PWL-based LCD Backlight"
121 depends on BACKLIGHT_CLASS_DEVICE && ARCH_OMAP1
124 This driver controls the LCD backlight level and power for
125 the PWL module of OMAP1 processors. Say Y if your board
128 config BACKLIGHT_HP680
129 tristate "HP Jornada 680 Backlight Driver"
130 depends on BACKLIGHT_CLASS_DEVICE && SH_HP6XX
133 If you have a HP Jornada 680, say y to enable the
136 config BACKLIGHT_PROGEAR
137 tristate "Frontpath ProGear Backlight Driver"
138 depends on BACKLIGHT_CLASS_DEVICE && PCI && X86
141 If you have a Frontpath ProGear say Y to enable the
144 config BACKLIGHT_CARILLO_RANCH
145 tristate "Intel Carillo Ranch Backlight Driver"
146 depends on BACKLIGHT_CLASS_DEVICE && LCD_CLASS_DEVICE && PCI && X86 && FB_LE80578
149 If you have a Intel LE80578 (Carillo Ranch) say Y to enable the
153 tristate "Generic PWM based Backlight Driver"
154 depends on BACKLIGHT_CLASS_DEVICE && HAVE_PWM
156 If you have a LCD backlight adjustable by PWM, say Y to enable
159 config BACKLIGHT_MBP_NVIDIA
160 tristate "MacBook Pro Nvidia Backlight Driver"
161 depends on BACKLIGHT_CLASS_DEVICE && X86
164 If you have an Apple Macbook Pro with Nvidia graphics hardware say Y
165 to enable a driver for its backlight
