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 "LCD Panel support for SHARP corgi/spitz model"
29 depends on LCD_CLASS_DEVICE && SPI_MASTER && PXA_SHARPSL
31 Say y here to support the LCD panels usually found on SHARP
32 corgi (C7x0) and spitz (Cxx00) models.
35 tristate "Samsung LTV350QV LCD Panel"
36 depends on LCD_CLASS_DEVICE && SPI_MASTER
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
44 The LTV350QV panel is present on all ATSTK1000 boards.
48 depends on LCD_CLASS_DEVICE && BACKLIGHT_LCD_SUPPORT
51 If you have a panel based on the ILI9320 controller chip
52 then say y to include a power driver for it.
55 tristate "VGG2432A4 LCM device support"
56 depends on BACKLIGHT_LCD_SUPPORT && LCD_CLASS_DEVICE && SPI_MASTER
60 If you have a VGG2432A4 panel based on the ILI9320 controller chip
61 then say y to include a power driver for it.
64 tristate "Platform LCD controls"
65 depends on LCD_CLASS_DEVICE
67 This driver provides a platform-device registered LCD power
73 config BACKLIGHT_CLASS_DEVICE
74 tristate "Lowlevel Backlight controls"
75 depends on BACKLIGHT_LCD_SUPPORT
78 This framework adds support for low-level control of the LCD
79 backlight. This includes support for brightness and power.
81 To have support for your specific LCD panel you will have to
82 select the proper drivers which depend on this option.
84 config BACKLIGHT_ATMEL_LCDC
85 bool "Atmel LCDC Contrast-as-Backlight control"
86 depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
87 default y if MACH_SAM9261EK || MACH_SAM9263EK
89 This provides a backlight control internal to the Atmel LCDC
90 driver. If the LCD "contrast control" on your board is wired
91 so it controls the backlight brightness, select this option to
92 export this as a PWM-based backlight control.
94 If in doubt, it's safe to enable this option; it doesn't kick
95 in unless the board's description says it's wired that way.
97 config BACKLIGHT_ATMEL_PWM
98 tristate "Atmel PWM backlight control"
99 depends on BACKLIGHT_CLASS_DEVICE && ATMEL_PWM
102 Say Y here if you want to use the PWM peripheral in Atmel AT91 and
103 AVR32 devices. This driver will need additional platform data to know
104 which PWM instance to use and how to configure it.
106 To compile this driver as a module, choose M here: the module will be
109 config BACKLIGHT_CORGI
110 tristate "Generic (aka Sharp Corgi) Backlight Driver"
111 depends on BACKLIGHT_CLASS_DEVICE
114 Say y to enable the generic platform backlight driver previously
115 known as the Corgi backlight driver. If you have a Sharp Zaurus
116 SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
118 config BACKLIGHT_LOCOMO
119 tristate "Sharp LOCOMO LCD/Backlight Driver"
120 depends on BACKLIGHT_CLASS_DEVICE && SHARP_LOCOMO
123 If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
124 enable the LCD/backlight driver.
126 config BACKLIGHT_OMAP1
127 tristate "OMAP1 PWL-based LCD Backlight"
128 depends on BACKLIGHT_CLASS_DEVICE && ARCH_OMAP1
131 This driver controls the LCD backlight level and power for
132 the PWL module of OMAP1 processors. Say Y if your board
135 config BACKLIGHT_HP680
136 tristate "HP Jornada 680 Backlight Driver"
137 depends on BACKLIGHT_CLASS_DEVICE && SH_HP6XX
140 If you have a HP Jornada 680, say y to enable the
143 config BACKLIGHT_PROGEAR
144 tristate "Frontpath ProGear Backlight Driver"
145 depends on BACKLIGHT_CLASS_DEVICE && PCI && X86
148 If you have a Frontpath ProGear say Y to enable the
151 config BACKLIGHT_CARILLO_RANCH
152 tristate "Intel Carillo Ranch Backlight Driver"
153 depends on BACKLIGHT_CLASS_DEVICE && LCD_CLASS_DEVICE && PCI && X86 && FB_LE80578
156 If you have a Intel LE80578 (Carillo Ranch) say Y to enable the
160 tristate "Generic PWM based Backlight Driver"
161 depends on BACKLIGHT_CLASS_DEVICE && HAVE_PWM
163 If you have a LCD backlight adjustable by PWM, say Y to enable
166 config BACKLIGHT_MBP_NVIDIA
167 tristate "MacBook Pro Nvidia Backlight Driver"
168 depends on BACKLIGHT_CLASS_DEVICE && X86
171 If you have an Apple Macbook Pro with Nvidia graphics hardware say Y
172 to enable a driver for its backlight
