Hi!
[ Upstream commit bee1f89aad2a51cd3339571bc8eadbb0dc88a683 ]
The xHCI driver support usb2 HW LPM by default, here add support XHCI_HW_LPM_DISABLE quirk, then we can disable usb2 lpm when need it.
This is only needed with corresponding DTS, and I don't see such DTS entry in mainline or stable.
We may not want this in stable.
Best regards, Pavel
