[PATCH 7/7] arm64: dts: qcom: ideacentre-mini: Drop the unused USB MP port
From: Jens Glathe via B4 Relay
Date: Sat Sep 05 2026 - 05:32:52 EST
From: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx>
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.
Tested-on: IdeaCentre Mini 01Q8X10, Purwa (X1-26-100)
Assisted-by: Grok 4.5 (xAI)
Signed-off-by: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx>
