[PATCH 0/3] phy: apple: atc: Prepare USB3-via-4 tunneling

From: Sven Peter

Date: Fri Aug 21 2026 - 09:51:15 EST


Hi,

This short series first fixes an oversight that prevents USB2 from
working when DP AltMode with 4 lanes is used. Then it adds the required
sequence to point dwc3's PIPE interface to the USB4 Native Host
Interface which I plan to submit soon to support USB3-via-USB4 tunnels.

Best,

Sven
