vbus-supply:
description: A phandle to the regulator for USB VBUS if needed when host
mode or dual role mode is supported.
Particularly, if use an output GPIO to control a VBUS regulator, should
model it as a regulator. See bindings/regulator/fixed-regulator.yaml

offer the power, Capability Mismatch is set. Required for power sink and
power dual role.
ports:
description: OF graph bindings (specified in bindings/graph.txt) that model
any data bus to the connector unless the bus is between parent node and
the connector. Since a single connector can have multiple data buses every
