Subject: [PATCH v2 2/8] dt-bindings: counter: Add new ti,am62-eqep compatible
Add new compatible ti,am62-eqep for TI K3 devices. If a device
uses this compatible, require power-domains property.
Since there is only one functional and interface clock for eqep,
clock-names is not really required. The clock-name also changed
for TI K3 SoCs so make clock-names optional for the new compatible
since there is only one clock that is routed to the IP.
While we are here, add an example using ti,am62-eqep compatible.
Signed-off-by: Judith Mendez <jm@...com>

Changes since v1:
- Fix eqep binding for new compatible, require
power-domains for new compatible
