Merge tag 'pwm/for-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"This set of changes introduces the beginnings of a new API that's
based around the concept of states that can be atomically applied.
Drivers go to various lengths to implement something similar, which
indicates that the core should really be providing the necessary
framework.
On top of that, there is a bit of cleanup as well as improved
kerneldoc and integration into the device-drivers DocBook.
Regarding drivers there is a new one for the NXP LPC18xx family of
SoCs and a couple of fixes for existing drivers (pca9685, Broadcom
Kona and Atmel HLCDC)"
