    Pull pwm changes from Thierry Reding:
     "All legacy PWM providers have now been moved to the PWM subsystem.
      The plan for 3.8 is to adapt all board files to provide a lookup table
      for PWM devices in order to get rid of the global namespace.
      Subsequently, users of the legacy pwm_request() and pwm_free()
      functions can be migrated to the new pwm_get() and pwm_put()
      functions.  Once this has been completed, the legacy API and the
      compatibility code in the core can be removed.
    
      In addition to the above, these changes also add support for
      configuring the polarity of a PWM signal (currently only supported on
      ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
      Managed functions to obtain and release a PWM device (devm_pwm_get()
      and devm_pwm_put()) have been added and the pwm-backlight driver has
      been updated to use them.  If the PWM subsystem hasn't been enabled,
      dummy functions are provided that allow the subsystem to safely
      compile out.
    
      Some common checks on input parameters have been moved to the core and
      removed from the drivers.  Finally, a small fix corrects the
      description of the PWM specifier's second cell in the device tree
      representation."
