Merge tag 'pwm/for-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This set of changes contains a new driver for OMAP (using the
  dual-mode timers) as well as an assortment of fixes all across the
  board"

* OMAP PWM for dual-mode timers



Required properties:

- compatible: Shall contain "ti,omap-dmtimer-pwm".

- ti,timers: phandle to PWM capable OMAP timer. See arm/omap/timer.txt for info

  about these timers.

- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of

  the cells format.



Optional properties:

- ti,prescaler: Should be a value between 0 and 7, see the timers datasheet



Example:

	pwm9: dmtimer-pwm@9 {

		compatible = "ti,omap-dmtimer-pwm";

		ti,timers = <&timer9>;

		#pwm-cells = <3>;

	};
