| A USB Type-C connector node represents a physical USB Type-C connector. |
| It should be a child of a USB-C interface controller or a separate node |
| when it is attached to both MUX and USB-C interface controller. |
| |
| This is based on Linux, documentation: |
| https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/connector/usb-connector.yaml?h=v5.19&id=3d7cb6b04c3f3115719235cc6866b10326de34cd |

| Example: |
| |
| USB-C connector attached to a STM32 UCPD typec port controller, which has |
| power delivery support and enables SINK. |
