[PATCH 0/3] Apple DWI backlight driver

[Nick Chan]

Apple SoCs come with a 2-wire interface named DWI. On some iPhones, iPads
and iPod touches 1-2 backlight controllers are attached via this interface.
Though, to software using this interface, there is effectively only one
controller to worry about since the registers changes the brightness
setting on all controllers at the same time. This series adds a backlight
driver for backlight controllers connected this way.
