Subject: [PATCH v5 0/7] pinctrl: intel: Enable PWM optional feature


This is a continuation of the previously applied PWM LPSS cleanup series.
Now, we would like to enable PWM optional feature that may be embedded
into Intel pin control IPs (starting from Sky Lake platforms).

I would like to route this via Intel pin control tree with issuing
an immutable branch for both PINCTRL and PWM subsystems, but I'm
open for other suggestions.

Hans, I dared to leave your Rb tags, however the patches are slightly
differ, because of the Uwe's suggestion on how to handle the missing
headers. I hope you are okay with that. If not, please comment what
must be amended then.

Uwe, the patches 3 and 6 still need your blessing.

Changelog v5:
- added more tags (Uwe)
- avoid moving struct pwm_lpss_chip in patch 3 (Uwe)
- simplified error checking in intel_pinctrl_probe_pwm() (Uwe)

Changelog v4:
- added patch "Rename pwm_lpss_probe() --> devm_pwm_lpss_probe()"

Changelog v3:
- added tags (Uwe, Linus, Thierry)
- fixed some spelling issues in the commit messages
- changed a paragraph in the commit message of the patch 3 (Uwe)
- replaced -ENODEV check with IS_REACHABLE() in the patch 6 (Uwe)

Changelog v2:
- added tag (Mika)
- added base-commit to the series, to make sure LKP can test it
