# Backlight & LCD drivers configuration

menuconfig BACKLIGHT_LCD_SUPPORT
bool "Backlight & LCD device support"
help
Enable this to be able to choose the drivers for controlling the
backlight and the LCD panel on some platforms, for example on PDAs.
#
# LCD
#
config LCD_CLASS_DEVICE
tristate "Lowlevel LCD controls"
depends on BACKLIGHT_LCD_SUPPORT
default m
help
This framework adds support for low-level control of LCD.
Some framebuffer devices connect to platform-specific LCD modules
in order to have a platform-specific way to control the flat panel
(contrast and applying power to the LCD (not to the backlight!)).
To have support for your specific LCD panel you will have to
select the proper drivers which depend on this option.
config LCD_LTV350QV
tristate "Samsung LTV350QV LCD Panel"
depends on LCD_CLASS_DEVICE && SPI_MASTER
default n
help
If you have a Samsung LTV350QV LCD panel, say y to include a
power control driver for it. The panel starts up in power
off state, so you need this driver in order to see any
output.
The LTV350QV panel is present on all ATSTK1000 boards.

# Backlight

config BACKLIGHT_CLASS_DEVICE
tristate "Lowlevel Backlight controls"
depends on BACKLIGHT_LCD_SUPPORT
default m
help
This framework adds support for low-level control of the LCD
backlight. This includes support for brightness and power.
To have support for your specific LCD panel you will have to
select the proper drivers which depend on this option.
config BACKLIGHT_ATMEL_LCDC
bool "Atmel LCDC Contrast-as-Backlight control"
depends on BACKLIGHT_CLASS_DEVICE && FB_ATMEL
default y if MACH_SAM9261EK || MACH_SAM9263EK
help
This provides a backlight control internal to the Atmel LCDC
driver. If the LCD "contrast control" on your board is wired
so it controls the backlight brightness, select this option to
export this as a PWM-based backlight control.
If in doubt, it's safe to enable this option; it doesn't kick
in unless the board's description says it's wired that way.
config BACKLIGHT_CORGI
tristate "Generic (aka Sharp Corgi) Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE
default n
help
Say y to enable the generic platform backlight driver previously
known as the Corgi backlight driver. If you have a Sharp Zaurus
SL-C7xx, SL-Cxx00 or SL-6000x say y. Most users can say n.
config BACKLIGHT_LOCOMO
tristate "Sharp LOCOMO LCD/Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE && SHARP_LOCOMO
default y
help
If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to
enable the LCD/backlight driver.
config BACKLIGHT_OMAP1
tristate "OMAP1 PWL-based LCD Backlight"
depends on BACKLIGHT_CLASS_DEVICE && ARCH_OMAP1
default y
help
This driver controls the LCD backlight level and power for
the PWL module of OMAP1 processors. Say Y if your board
uses this hardware.
config BACKLIGHT_HP680
tristate "HP Jornada 680 Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE && SH_HP6XX
default y
help
If you have a HP Jornada 680, say y to enable the
backlight driver.
config BACKLIGHT_PROGEAR
tristate "Frontpath ProGear Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE && PCI && X86
default n
help
If you have a Frontpath ProGear say Y to enable the
backlight driver.
config BACKLIGHT_CARILLO_RANCH
tristate "Intel Carillo Ranch Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE && LCD_CLASS_DEVICE && PCI && X86 && FB_LE80578
default n
help
If you have a Intel LE80578 (Carillo Ranch) say Y to enable the
backlight driver.
config BACKLIGHT_PWM
tristate "Generic PWM based Backlight Driver"
depends on BACKLIGHT_CLASS_DEVICE && HAVE_PWM
help
If you have a LCD backlight adjustable by PWM, say Y to enable
this driver.
