Hello,

The patch:
https://lkml.org/lkml/2012/11/7/187
grown to be a series to add DeviceTree support for the leds-pwm driver.

Changes since v1:
- As suggested by Bryan Wu: the legacy pwm_request() has been removed from
  patch 1
- Device tree bindings added for leds-pwm driver.

When we boot with Device tree we handle one LED per device to be more aligned
with PWM core's DT implementation.
An example of the DT usage is provided in the new DT binding documentation for
leds-pwm.

Tested on OMAP4 Blaze (SDP) with legacy and DT boot.

Regards,
Peter
