Subject: [PATCH v3 0/4] 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.

Uwe,
Patches #3 and #4 conflict with patches #18 and #68 of your pwm rework [3]
I understand such wide rework are difficult to handle. I don't mind
handling the rebase of the amlogic patches you have proposed if this gets
in first. Just let me know :)

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

Jerome Brunet (4):
  dt-bindings: pwm: amlogic: fix s4 bindings
  dt-bindings: pwm: amlogic: add new compatible for meson8 pwm type
  pwm: meson: prepare addition of new compatible types
  pwm: meson: add generic compatible for meson8 to sm1
