But I think it should still apply, please double check. Regardless, Acked-by: Thinh Nguyen <Thinh.Nguyen@synopsys.com> Thanks, Thinh

Add 2 software manage quirk properties (xhci-missing-cas-quirk and xhci-skip-phy-init-quirk) for xhci host. dwc3 driver have PHY management to cover both device and host mode, so add xhci-skip-phy-init-quirk to skip PHY management from HCD core. Cold Attach Status (CAS) bit can't be set at i.MX8MP after resume from suspend state. So set xhci-missing-cas-quirk.
