[PATCH 2/2] usb: host: xhci-plat: enable XHCI_MISSING_CAS if platform requested

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In case there is CAS missing if device plugged in S3, we can use
'usb3-resume-missing-cas' device property to enable quirk flag
XHCI_MISSING_CAS.
