Subject: [PATCH 1/3] mfd: ab8500-pwm: ab8500 pwm management
Date: Wednesday, August 25, 2010 - 11:50 pm

This patch exports functions to set and get ab8500 pwm intensity,
which in turn is used by backlight/led driver.

There are drivers/leds/leds-pwm.c and drivers/video/backlight/pwm_bl.c that 
implement led and backlight drivers based on generic pwm interface.
