From 7be865ab8634d4ec2a6bdb9459b268cd60e832af Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Fri, 23 Mar 2012 15:02:01 -0700 Subject: backlight: new backlight driver for LP855x devices THis driver supports TI LP8550/LP8551/LP8552/LP8553/LP8556 backlight devices. The brightness can be controlled by the I2C or PWM input. The lp855x driver provides both modes. For the PWM control, pwm-specific functions can be defined in the platform data. And some information can be read via the sysfs(lp855x device attributes). For details, please refer to Documentation/backlight/lp855x-driver.txt.
