Re: [PATCH] dt-bindings: extcon: ti,extcon-palmas: Convert to DT schema

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The device tree node name in the example uses an underscore (`palmas_usb`), which violates standard DT naming conventions. It should use a hyphen (e.g., `palmas-usb` or a generic name like `usb-comparator`). This change introduces a `dtc` warning (`node_name_chars_strict`) during `make dt_binding_check` that was not present in the original text binding.

dt-bindings: extcon: ti,extcon-palmas: Convert to DT schema
    
This commit converts the Texas Instruments Palmas USB Comparator binding from
the legacy text format to a modern DT schema.

[Severity: Low]
Is the underscore in this node name intentional? 

The original text binding used a hyphen (palmas-usb). Using an underscore
violates standard device tree naming conventions and will trigger a dtc 
node_name_chars_strict warning during make dt_binding_check.

Would it be better to stick with the original palmas-usb or use a generic
node name like usb-comparator?
