[PATCHv2 0/2] backlight: Add TI LMU backlight driver

[Sebastian Reichel]

Hi,

This adds backlight support for TI LMU devices. I updated the
patches from Milo Kim according to the comments from Daniel
Thompson and tested the result on Droid 4.

Changes since PATCHv1 [0]:
 * split dt-binding documentation in its own patch
 * move include/linux/mfd/ti-lmu-backlight.h to drivers/video/backlight/ti-lmu-backlight-data.h
 * replace LMU_BL_REG() with a normal struct
 * add "const" keyword to lots of internal structures
 * improve error handling
 * use atomic pwm api
