Linus Torvalds ecc5fbd5ef pwm: Changes for v4.7-rc1
This set of changes introduces an atomic API to the PWM subsystem. This
 is influenced by the DRM atomic API that was introduced a while back,
 though it is obviously a lot simpler. The fundamental idea remains the
 same, though: drivers provide a single callback to implement the atomic
 configuration of a PWM channel.
 
 As a side-effect the PWM subsystem gains the ability for initial state
 retrieval, so that the logical state mirrors that of the hardware. Many
 use-cases don't care about this, but for others it is essential.
 
 These new features require changes in all users, which these patches
 take care of. The core is transitioned to use the atomic callback if
 available and provides a fallback mechanism for other drivers.
 
 Changes to transition users and drivers to the atomic API are postponed
 to v4.8.
