-Required properties:
- - compatible: Must be "ti,hd3ss3220".
- - reg: I2C slave address, must be 0x47 or 0x67 based on ADDR pin.
- - interrupts: An interrupt specifier.

+description: |-
+  HD3SS3220 is a USB SuperSpeed (SS) 2:1 mux with DRP port controller. The device provides Channel
+  Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. The
+  HD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP) or a
+  Dual Role Port (DRP) making it ideal for any application.
