Alberto Panizzo e7fb9c4ad3 backlight: Add Epson L4F00242T03 LCD driver
The Epson LCD L4F00242T03 is mounted on the Freescale i.MX31 PDK board. 
Based upon Marek Vasut work in l4f00242t03.c, this driver provides
basic init and power on/off functionality for this device through the
sysfs lcd interface.

Unfortunately Datasheet for this device are not available and
all the control sequences sent to the display were copied from the
freescale driver that in the i.MX31 Linux BSP.

As in the i.MX31PDK board the core and io suppliers are voltage
regulators, that functionality is embedded here, but not strict.

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.

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.
