This patch adds support for powering on and off the Samsung LTV350QV LCD panel via SPI. The driver responds to framebuffer power management, it powers off the panel on reboot/halt/poweroff. It can also be controlled through sysfs. The panel is powered up when the module is loaded, and off when the module is unloaded. Verified on AVR32 STK1000.

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.
