Subject: [PATCH v2 0/6] pwm: mxs: add support for setting polarity via DT

This series adds support for setting the polarity via DT to the
pwm-mxs driver.

The DT binding is updated, but I'm not touching the existing .dts or
.dtsi files - it seems that the same was done for bcm2835 in commits
46421d9d8e802e570dfa4d793a4938d2642ec7a7 and
8a88b2a2017d1e7e80db53080baff591fd454722, while
arch/arm/boot/dts/bcm283x.dtsi still has #pwm-cells = <2>.

v2:
- Rebase to v5.4-rc1
- Address comments from Uwe.
- Add Rob's ack to patch 4.
- New patches 5 and 6. The last one is independent of the others, but
  I stumbled on this when rebasing and found the signature had
  changed.

Rasmus Villemoes (6):
  pwm: mxs: implement ->apply
  pwm: mxs: remove legacy methods
  pwm: mxs: add support for inverse polarity
  dt-bindings: pwm: mxs-pwm: Increase #pwm-cells
  pwm: mxs: avoid a division in mxs_pwm_apply()
  pwm: update comment on struct pwm_ops::apply
