Use 'interrupts'. The tooling will automatically support

Where's the data connections? The assumption of the binding is the USB 
(2 and 3) connections come from the parent if there's no graph to the 
USB controller(s).

Also, this is not a pattern, so should be under 'properties', and it 
doesn't need quotes.

MT6360 is only a subpmic. TypeC part only handle the CC logic to support USBPD.
For the usb connection like as usbhs/usbss,  it need to be handled
by/connect to application processor side.
LIke as connector/usb-connector.yaml decribed, it  specify the port
property to bind USB HS/SS.

Do i need to add the ports into the connector node for example?
Like as hs/ss/aux, to make the user know to use 6360's tcpc?

I check the  style in connector/usb-connect.yaml
Do I also need to replace two space instead of one tab in the binding example?
