Subject: [RFC PATCH v3 0/4] Add usb2 link powermanagement BESL support
Date: Thu, 23 May 2013 17:14:27 +0300 [thread overview]
Message-ID: <1369318471-10353-1-git-send-email-mathias.nyman@linux.intel.com> (raw)
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.
Changes since v1:
-Use kstrto* and unsigned values in sysfs functions as Alan Stern suggested
Changes since v2:
- Add Documentation/ABI/testing/sysfs-bus-usb entries for new sysfs attributes
- store l1_timeout value in microseconds instead of xHCI specific values
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
