This series:
- drops a redundant compatible
- converts tiehrpwn to DT schema format using json-schema
- Add new compatible for AM64 SoC.
Changes since v1:
- Updated the am64 compatible to ti,am64-epwm as High resolution is not
supported.

dt-bindings: pwm: tiehrpwm: Make clock and clock-names as required
properties
dt-bindings: pwm: pwm-tiehrpwm: Convert to json schema
dt-bindings: pwm: pwm-tiehrpwm: Add compatible string for AM64 SoC

Commit 229110c1aa691 ("ARM: dts: am437x/am33xx/da850: Add new ECAP and
EPWM bindings") added ti,am3352-ehrpwm compatible which is similar to
ti,am33xx-ehrpwm but without out t,hwmod properties. But with commit
58bfbea5b1c68 ("ARM: dts: am437x/am33xx: Remove hwmod entries for ECAP
and EPWM nodes") dropped support for all ti,hwmod for ehrpwm, but
missed deprecating ti,am33xx-ehrpwm compatible. So drop ti,am33xx-ehrpwm
from DT as it is no longer needed.
ti-ehrpwn driver still support ti,am33xx-ehrpwm in order to maintain
backward compatibility.

* [PATCH v2 2/4] dt-bindings: pwm: tiehrpwm: Make clock and clock-names as required properties

Driver fails to probe when 'clock' and 'clock-names' properties are not
populated in DT. But the binding documentation says these properties are
optional. Fix this by making 'clock' and 'clock-names' properties as
required.

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.
