Hi, This patch series is about to add a sysfs attribute, through which users can disable or enable USB3 LPM (link power management) from a USB port. Once LPM is disabled from the USB port, LPM between the downstreaming device and the hub port will not be activated. This helps users to use any LPM-unfriendly USB devices on any released Linux kernels.
This patch series contains a fix and a cleanup as well. Thanks, Baolu Lu Baolu (3): usb: core: lpm: fix usb3_hardware_lpm sysfs node usb: core: lpm: add sysfs node for usb3 lpm permit usb: core: lpm: remove usb3_lpm_enabled in usb_device Documentation/ABI/testing/sysfs-bus-usb | 27 +++++++--- Documentation/usb/power-management.txt | 11 ++-- drivers/usb/core/hub.c | 33 +++++++++--- drivers/usb/core/hub.h | 5 +- drivers/usb/core/port.c | 89 ++++++++++++++++++++++++++++++++- drivers/usb/core/sysfs.c | 31 ++++++++++-- include/linux/usb.h | 3 +- 7 files changed, 172 insertions(+), 27 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
