SubjectRe: [PATCH v3 1/2] dt-bindings: chrome: Add cros-ec-typec mux props
Hi Rob,

Would you prefer these switches to be defined in the
usb-connector.yaml bindings file?
If there are no other concerns, I can push a fresh version of the
patch with the properties defined in usb-connector.yaml.

Thanks,
