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.
59 config BACKLIGHT_CLASS_DEVICE
60 tristate "Lowlevel Backlight controls"
61 depends on BACKLIGHT_LCD_SUPPORT
64 This framework adds support for low-level control of the LCD
65 backlight. This includes support for brightness and power.
67 To have support for your specific LCD panel you will have to
68 select the proper drivers which depend on this option.
70 config BACKLIGHT_ATMEL_LCDC
71 bool "Atmel LCDC Contrast-as-Backlight control"
72 depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
73 default y if MACH_SAM9261EK || MACH_SAM9263EK
75 This provides a backlight control internal to the Atmel LCDC
76 driver. If the LCD "contrast control" on your board is wired
77 so it controls the backlight brightness, select this option to
78 export this as a PWM-based backlight control.
80 If in doubt, it's safe to enable this option; it doesn't kick
81 in unless the board's description says it's wired that way.
83 config BACKLIGHT_CORGI
84 tristate "Generic (aka Sharp Corgi) Backlight Driver"
85 depends on BACKLIGHT_CLASS_DEVICE
88 Say y to enable the generic platform backlight driver previously
89 known as the Corgi backlight driver. If you have a Sharp Zaurus
90 SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
92 config BACKLIGHT_LOCOMO
93 tristate "Sharp LOCOMO LCD/Backlight Driver"
94 depends on BACKLIGHT_CLASS_DEVICE && SHARP_LOCOMO
97 If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
98 enable the LCD/backlight driver.
100 config BACKLIGHT_OMAP1
101 tristate "OMAP1 PWL-based LCD Backlight"
102 depends on BACKLIGHT_CLASS_DEVICE && ARCH_OMAP1
105 This driver controls the LCD backlight level and power for
106 the PWL module of OMAP1 processors. Say Y if your board
109 config BACKLIGHT_HP680
110 tristate "HP Jornada 680 Backlight Driver"
111 depends on BACKLIGHT_CLASS_DEVICE && SH_HP6XX
114 If you have a HP Jornada 680, say y to enable the
117 config BACKLIGHT_PROGEAR
118 tristate "Frontpath ProGear Backlight Driver"
119 depends on BACKLIGHT_CLASS_DEVICE && PCI && X86
122 If you have a Frontpath ProGear say Y to enable the
125 config BACKLIGHT_CARILLO_RANCH
126 tristate "Intel Carillo Ranch Backlight Driver"
127 depends on BACKLIGHT_CLASS_DEVICE && LCD_CLASS_DEVICE && PCI && X86 && FB_LE80578
130 If you have a Intel LE80578 (Carillo Ranch) say Y to enable the
134 tristate "Generic PWM based Backlight Driver"
135 depends on BACKLIGHT_CLASS_DEVICE && HAVE_PWM
137 If you have a LCD backlight adjustable by PWM, say Y to enable
