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 Documentation/ABI/testing/sysfs-bus-usb | 27 ++++ drivers/usb/core/sysfs.c | 54 +++++++ drivers/usb/host/xhci-ext-caps.h | 1 + drivers/usb/host/xhci-hub.c | 16 +-- drivers/usb/host/xhci-mem.c | 33 ++++- drivers/usb/host/xhci.c | 237 ++++++++++++++++++++++--------- drivers/usb/host/xhci.h | 29 ++++ include/linux/usb.h | 20 +++ 8 files changed, 337 insertions(+), 80 deletions(-) -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
