These patches provides support of LPM capability to the dwc3 xhci hosts.
LPM capability is disabled by default. Any dwc3 based platform can enable
it through device tree.
Patches have been tested on STih407 by Aymen BOUATTAY.

Hi Alan/Greg,
I was starting some work for running "Lecroy USB Compliance Suite Link
Layer Tests" with embedded xhci host, which runs Linux. I thought, its
wise to discuss my test strategy before I start implementing it,
as in long run I would like to push them to mainline.
These tests have been
Hi Sarah,
Thanks a lot for replying back.

Hi Sarah,
I have to implement dynamic U1/U2 initiation on a dwc3 based xhci
platform. I can see that my host starts sending LGO_U1 (when idle) by
enabling XHCI_LPM_SUPPORT & XHCI_INTEL_HOST quirk in xhci_plat_quirks
and using xhci_enable/disable_usb3_lpm_timeout in
xhci_plat_xhci_driver. But offc
