dts validation is throwing an error for me on 8916 and 8939 with
extcon@1300. In that case we have usb_vbus but not usb_id.
It wasn't immediately obvious if there was a valid use-case for the
existing code for usb_id in isolation, however discussing further, we
concluded that usb_id, usb_vbus or (usb_id | usb_vbus) are valid
combinations as an external IC may be responsible for usb_id or usb_vbus.
Expand the definition with anyOf to capture the three different valid
modes.

Some Qualcomm PMICs have a "misc" module that can be used to detect when
|
|
the USB ID pin has been pulled low or high.
