Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] DT Schema validation failure due to mismatched interrupt order in examples.
- [Low] DT Binding ABI Breakage by enforcing a backward-incompatible interrupt order.

dt-bindings: phy: motorola,cpcap-usb: add chrg_det interrupt
The CPCAP USB PHY driver uses the CPCAP charger detection interrupt
for DCP detection. Update the binding and example DTS to use the
corresponding chrg_det interrupt name.

[Severity: Low]
Does adding this new interrupt in the middle of the items list break backward
compatibility for existing device trees?
By inserting it at index 7 (before dm and dp) without configuring minItems, the
schema now implicitly requires all 10 items in this strict order.
Existing device trees that only define 9 interrupts will fail validation because
their 7th item is dm instead of chrg_det.

[Severity: Low]
Will this example pass dt_binding_check validation?
The schema's properties block was updated above to expect chrg_det at index 7,
before dm and dp. However, the example appends chrg_det to the end of the list
at index 9.
YAML lists enforce positional matches, so validation might fail when it compares
the example's dm at index 7 against the newly expected chrg_det.
