[linux-yocto] [PATCH 09/10] UPSTREAM: pwm: Use pwm_get/set_xxx() helpers where appropriate

From: Boris Brezillon <boris.brezillon at free-electrons.com>

Use pwm_get/set_xxx() helpers instead of directly accessing the pwm->xxx
field. Doing that will ease adaptation of the PWM framework to support
atomic update.

CONFLICTS:
  This patch originally fixed up omap-dmtimer as well, which does not
  yet exist in the 4.4 kernel.
