Subject: [PWM PATCH 0/7] Generic PWM API

This series implements a generic PWM device API.

Bill Gatliff (7):
  API to consolidate PWM devices behind a common user and kernel
    interface
  Emulates PWM hardware using a high-resolution timer and a GPIO pin
  Expunge old Atmel PWMC driver, replacing it with one that conforms to
    the PWM API
  Implements PWM-based LED control
  LED "dim" trigger based on PWM control of the LED
  Incorporate PWM API code into KBuild
  PWM API driver for MPC52xx GPT peripheral
