+description:
+  The Type-C PHY (ACIOPHY) of the Apple T8152 (M6) SoC, used as the USB3 PHY
+  of a port that is wired to a fixed USB3 device instead of a Type-C
+  connector, such as the on-board hub behind the Mac mini (2026) front ports.
+  The PHY also switches the PIPE handler of its DWC3 controller between the
+  controller's dummy PHY and the ACIOPHY.
