Enable this to be able to choose the drivers for controlling the backlight and the LCD panel on some platforms, for example on PDAs.
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.
Say y here to support the LCD panels usually found on SHARP corgi (C7x0) and spitz (Cxx00) models.
SPI driver for Epson L4F00242T03. This provides basic support for init and powering the LCD up/down through a sysfs interface.
SPI driver for Samsung LMS283GF05. This provides basic support for powering the LCD up/down through a sysfs interface.
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.
If you have a panel based on the ILI9320 controller chip then say y to include a power driver for it.
If you have a Toppoly TDO24M/TDO35S series LCD panel, say y here to include the support for it.
If you have a VGG2432A4 panel based on the ILI9320 controller chip then say y to include a power driver for it.
This driver provides a platform-device registered LCD power control interface.
If you have an Sharp SL-6000 Zaurus say Y to enable a driver for its LCD.
If you have an HP Jornada 700 series handheld (710/720/728) say Y to enable LCD control driver.
If you have an S6E63M0 LCD Panel, say Y to enable its LCD control driver.
If you have an LD9040 Panel, say Y to enable its control driver.
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.
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.
Say Y here if you want to use the PWM peripheral in Atmel AT91 and AVR32 devices. This driver will need additional platform data to know which PWM instance to use and how to configure it. To compile this driver as a module, choose M here: the module will be called atmel-pwm-bl.
If you have a LCD backlight connected to the BRIGHT output of the EP93xx, say Y here to enable this driver. To compile this driver as a module, choose M here: the module will be called ep93xx_bl.
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.
If you have a Sharp Zaurus SL-5500 (Collie) or SL-5600 (Poodle) say y to enable the LCD/backlight driver.
This driver controls the LCD backlight level and power for the PWL module of OMAP1 processors. Say Y if your board uses this hardware.
If you have a HP Jornada 680, say y to enable the backlight driver.
If you have an HP Jornada 700 series, say Y to include backlight control driver.
If you have a Frontpath ProGear say Y to enable the backlight driver.
If you have a Intel LE80578 (Carillo Ranch) say Y to enable the backlight driver.
If you have a LCD backlight adjustable by PWM, say Y to enable this driver.
If you have a LCD backlight connected to the WLED output of DA9030 or DA9034 WLED output, say Y here to enable this driver.
If you have a LCD backlight connected to the WLED output of MAX8925 WLED output, say Y here to enable this driver.
If you have an Intel-based Apple say Y to enable a driver for its backlight.
If you have an Sharp SL-6000 Zaurus say Y to enable a driver for its backlight
If you have a Tabletkiosk Sahara Touch-iT, say y to enable the backlight driver.
If you have a backlight driven by the ISINK and DCDC of a WM831x PMIC say y to enable the backlight driver for it.
Say Y to enable the backlight driver on Avionic Design Xanthos-based boards.
If you have a LCD backlight connected to the BST/BL_SNK output of ADP5520 or ADP5501, say Y here to enable this driver. To compile this driver as a module, choose M here: the module will be called adp5520_bl.
If you have a LCD backlight connected to the ADP8860, ADP8861 or ADP8863 say Y here to enable this driver. To compile this driver as a module, choose M here: the module will be called adp8860_bl.
If you have a LCD backlight connected to the ADP8870, say Y here to enable this driver. To compile this driver as a module, choose M here: the module will be called adp8870_bl.
Say Y to enable the backlight driver for Marvell 88PM8606.
If you have a backlight driven by a NXP PCF50633 MFD, say Y here to enable its driver.
