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.
42 config BACKLIGHT_CLASS_DEVICE
43 tristate "Lowlevel Backlight controls"
44 depends on BACKLIGHT_LCD_SUPPORT
47 This framework adds support for low-level control of the LCD
48 backlight. This includes support for brightness and power.
50 To have support for your specific LCD panel you will have to
51 select the proper drivers which depend on this option.
53 config BACKLIGHT_ATMEL_LCDC
54 bool "Atmel LCDC Contrast-as-Backlight control"
55 depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
56 default y if MACH_SAM9261EK || MACH_SAM9263EK
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.
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.
66 config BACKLIGHT_CORGI
67 tristate "Generic (aka Sharp Corgi) Backlight Driver"
68 depends on BACKLIGHT_CLASS_DEVICE
71 Say y to enable the generic platform backlight driver previously
72 known as the Corgi backlight driver. If you have a Sharp Zaurus
73 SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
75 config BACKLIGHT_LOCOMO
76 tristate "Sharp LOCOMO LCD/Backlight Driver"
77 depends on BACKLIGHT_CLASS_DEVICE && SHARP_LOCOMO
80 If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
81 enable the LCD/backlight driver.
83 config BACKLIGHT_OMAP1
84 tristate "OMAP1 PWL-based LCD Backlight"
85 depends on BACKLIGHT_CLASS_DEVICE && ARCH_OMAP1
88 This driver controls the LCD backlight level and power for
89 the PWL module of OMAP1 processors. Say Y if your board
92 config BACKLIGHT_HP680
93 tristate "HP Jornada 680 Backlight Driver"
94 depends on BACKLIGHT_CLASS_DEVICE && SH_HP6XX
97 If you have a HP Jornada 680, say y to enable the
100 config BACKLIGHT_PROGEAR
101 tristate "Frontpath ProGear Backlight Driver"
102 depends on BACKLIGHT_CLASS_DEVICE && PCI && X86
105 If you have a Frontpath ProGear say Y to enable the
108 config BACKLIGHT_CARILLO_RANCH
109 tristate "Intel Carillo Ranch Backlight Driver"
110 depends on BACKLIGHT_CLASS_DEVICE && LCD_CLASS_DEVICE && PCI && X86 && FB_LE80578
113 If you have a Intel LE80578 (Carillo Ranch) say Y to enable the
117 tristate "Generic PWM based Backlight Driver"
118 depends on BACKLIGHT_CLASS_DEVICE && HAVE_PWM
120 If you have a LCD backlight adjustable by PWM, say Y to enable
