[PATCH v3 0/2] dt-bindings: pwm: pwm-tiehrpwm: Convert to json schema

[Lokesh Vutla]

This series:
- converts tiehrpwn to DT schema format using json-schema
- Add new compatible for AM64 SoC.

Changes since v2 (https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=489981):
- Dropped DT changes from this series.

Changes since v1:
- Updated the am64 compatible to ti,am64-epwm as High resolution is not
  supported.

[PATCH v3 1/2] dt-bindings: pwm: pwm-tiehrpwm: Convert to json schema

[Lokesh Vutla]

Convert the tiehrpwm binding to DT schema format using json-schema.
Along with this conversion the following changes are included:
- 'clock' and 'clock-names' properties are marked as required as
   driver fails to probe without these properties
- Dropped ti,am33xx-ehrpwm as it is no longer applicable.
- 'power-domains' property is introduced and marked as optional.

[PATCH v3 2/2] dt-bindings: pwm: pwm-tiehrpwm: Add compatible string for AM64 SoC

[Lokesh Vutla]

Add compatible string for AM64 SoC in device tree binding.
EPWM IP in AM64 does not support High resolution, so named epwm instead
of ehrpwm in compatible. However IP is till compatible with features
supported by driver with ti,am3352-ehrpwm compatible.
