2014-05-08	leds: leds-pwm: add DT support for LEDs wired to supply	Russell King
	The non-DT driver allowed an active low property to be specified, but DT is missing this in its description. Add the property to the DT binding document, making it optional. It defaults to active high, which retains compatibility with existing descriptions. This should only be used for causes where the LED is wired to supply, and the PWM does not sensibly support its own inversion.

2013-02-01	leds: leds-pwm: Add device tree bindings	Peter Ujfalusi
	The DT binding for the pwm-leds devices are similar to the gpio-leds type. LEDs are represented as sub-nodes of the pwm-leds device. The code for handling the DT boot is based on the code found in the leds-gpio driver and adapted to use PWMs instead of GPIOs. To avoid having custom cleanup code in case of DT boot the newly created devm_of_pwm_get() API is used to get the correct PWM instance.
