* Added a new driver (apple_dwi_bl) for these controllers found
on some Apple mobile devices.
* Added MAINTAINERS entries for the new driver.

description:
|

Apple SoCs contain a 2-wire interface called DWI. On some Apple iPhones,
|
||||
iPads and iPod touches with a LCD display, 1-2 backlight controllers
|
||||
are connected via DWI. Interfacing with DWI controls all backlight
|
||||
controllers at the same time. As such, the backlight controllers are
|
||||
treated as a single controller regardless of the underlying
|
||||
configuration.
