Subject: [PATCH 0/4] Add haptics support to Nexus 5 using pwm-vibra driver

A while ago Brian Masney sent some patches for a clk-vibrator which was
then succeeded by the idea of a clk-pwm driver that "converts" a clock
into a PWM and to use the existing pwm-vibra driver.

Since clk-pwm has landed last year we can finally add haptics support
upstream.

We just need to add support for an enable GPIO to the pwm-vibra driver
since that also needs to be high for the haptics to work on this device.
