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.
