But was the idea really to put properties like the TCPC capabilities
under the usb connector child node? That will force us to extract
the same properties in two different methods in every USB Type-C
driver. One extracting them from DT, and another from other FW
interfaces and build-in properties.
To avoid that, let's just expect to get these properties in the node
for tcpc, not the usb connector child.
