fbdev: LCD backlight driver using Atmel PWM driver
This patch adds a platform driver using the ATMEL PWM driver to control a
backlight which requires a PWM signal and optional GPIO signal for discrete
on/off signal. It has been tested on Favr-32 board from EarthLCD.
The driver is configurable by supplying a struct with the platform data. See
the include/linux/atmel-pwm-bl.h for details.
The board code for Favr-32 will be submitted to the AVR32 kernel list.
