[PATCH v5 0/5] pwm: meson: dt-bindings fixup

This patchset aims to:
* Fix the incorrect bindings for the s4 type of pwm that was introduced
while converting the documentation from txt to yaml format.
* Introduce a new compatible for the existing PWMs to better describe the
HW in DT, instead of describing driver settings.
* Make the introduction of a new pwm variant (s4) slightly easier.

Changes since v4 [4]:
* Rebased on Uwe's pwm rework in pwm-next
* Drop change to carry device data in drvdata
* Make the length of parent name array fixed
* Single allocation instead 3 for the internal clock elements
* meson8-pwm-v2 and meson-pwm-s4 compatibles under an enum instead of
2 const

Changes since v3 [3]:
* Split first rework patch into 3 changes
* Use dev_warn_once() to notify use of obsolete bindings
* Rebased on Uwe dev_err_probe() change.

Changes since v2 [2]:
* Drop DTS changes. These will be re-submitted later on. Possibly after
u-boot gets support for the new compatible to minimise conversion
problems.
* Position deprecated property correctly in dt-bindings for the old
meson8 type pwm bindings
* Reword commit description of patch #2 to make more obvious it does not
introduce a new HW support but fixes a bad bindings.
* Dropped Rob's Reviewed-by on patch #2. It seemed appropriate considering
the discussion on this change.

Changes since v1 [1]:
* Fix typo in the new binding compatible documentation
* Disallow clock-names for the new compatibles in the schema documenation
