Subject: [PATCH v3] Skip phy initialization for DWC3 USB Controllers
Date: Wed, 1 Dec 2021 11:45:37 +0530 [thread overview]
Message-ID: <1638339338-6731-1-git-send-email-quic_c_sanm@quicinc.com> (raw)
Set XHCI_SKIP_PHY_INIT quirk to avoid phy initialization twice.
Runtime suspend of phy drivers was failing from DWC3 driver as
runtime usage value is 2 because the phy is initialized from
DWC3 core and HCD core.
DWC3 manages phy in their core drivers.
Set this quirk to avoid phy initialization in HCD core.
v3:
Dropped the dt property and binding.
Checking for dwc3 compatible in xhci to set the quirk XHCI_SKIP_PHY_INIT.
v2:
Updated the commit descriptions.
Changed subject prefix from dwc to dwc3.
Increased props array size.
