Linus Torvalds 2474542f64 pwm: Changes for v3.7-rc1 
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.
