Subject: Droid 4 backlight support

Hi!

Good news .. we have driver for backlight in mainline, AFAICT.

Bad news .. it is called "lm3532::backlight" or something like that. I
guess we should switch to ":backlight" or something? It is quite
important to do that before someone starts to use the ABI...

And now... we have the driver, but it is not connected to the
backlight subsystem. I guess we could make the LED "default on" for
now... but if there's better plan, let me know.

Best regards,
									Pavel
