Subject: [PATCH v4 0/6] 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 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

Jerome Brunet (6):
  dt-bindings: pwm: amlogic: fix s4 bindings
  dt-bindings: pwm: amlogic: add new compatible for meson8 pwm type
  pwm: meson: generalize 4 inputs clock on meson8 pwm type
  pwm: meson: use device data to carry information around
  pwm: meson: don't carry internal clock elements around
  pwm: meson: add generic compatible for meson8 to sm1
