This series adds usb2 best effort service latency (BESL) link PM support
to xHCI. BESL is an updated alternative to host initated resume delay
(HIRD) method of describing idle link timeouts.
Additionally this series fixes port capability checking
and replaces magic numbers with port register names.
Mathias Nyman (4):
usb: xhci: check usb2 port capabilities before adding hw link PM
support
usb: xhci: define port register names and use them instead of magic
numbers
usb: xhci: add USB2 Link power management BESL support
usb: add usb2 Link PM variables to sysfs and usb_device
