[PATCH 0/4] PWM and keyboard backlight driver for ARM Macs

From: Sasha Finkelstein

Hi,

This series adds support for the PWM controller present on ARM Macs and used
among other things for the keyboard backlight on those laptops.

The included device tree patch also hooks up the keyboard backlight using
the pwm-leds binding.

Best Regards.
