[PATCH v3 0/6] pwm: ensure pwm_apply_state() doesn't modify the state argument

["Uwe Kleine-König" <uwe-rXY34ruvC2xidJT2blvkqNi2O/JbrIOy@public.gmane.org>]

Hello,

this series eventually changes the prototype of pwm_apply_state to take
a const struct pwm_state *, see the last patch for a rationale.

Changes since v2 apart from rebasing and so covering a few more drivers
is mainly addressing the concern that after state was rounded and
applied at least pwm_get_state should return the rounded values. See
patch 2.

Uwe Kleine-König (6):
  pwm: introduce local struct pwm_chip in pwm_apply_state()
  pwm: let pwm_get_state() return the last implemented state
  pwm: rockchip: Don't update the state for the caller of
    pwm_apply_state()
  pwm: sun4i: Don't update the state for the caller of pwm_apply_state()
  pwm: fsl-ftm: Don't update the state for the caller of
    pwm_apply_state()
  pwm: ensure pwm_apply_state() doesn't modify the state argument
