From: Jens Glathe <redacted> usb_mp port 1 (hsphy1, qmpphy1, PTN3222 @ 0x4f, TLMM 184) is not populated. lsusb only shows two xHCI controllers: USB-C on usb_1_ss0 and the rear ports behind a Genesys hub on usb_mp port 0. Remove that repeater, its reset pin, and the second MP PHYs. Pin usb_mp to usb2-0 / usb3-0 so the controller does not claim empty PHYs.
