Re: [PATCH v2] dt-bindings: pwm: Convert TI PWM Subsystem to DT schema

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The newly added YAML binding example contains child nodes (ECAP, EQEP, and EHRPWM) that omit mandatory properties required by their respective device tree schemas, which will cause `make dt_binding_check` to fail.

dt-bindings: pwm: Convert TI PWM Subsystem to DT schema

Convert the Texas Instruments SoC PWM Subsystem bindings to DT schema. 
During the conversion, a 'counter' node was added to the allowed child
nodes list to resolve dtbs_check warnings.

[Severity: Low]
Will this example fail dt_binding_check validation?

These child nodes omit properties that are mandatory in their respective device
tree schemas. For instance, the ECAP and EHRPWM nodes are missing clocks and
clock-names, and the EQEP node is missing clocks and interrupts.

Since dt_binding_check cross-validates examples against all existing schemas,
omitting these required properties will likely trigger validation errors.
