[PATCH V5 0/10] usb: usb port power off mechanism and expose usb port connect type
Change since v1: optimize the export connect type patch and adjust the DeviceRemovalbe flag in the rh_call_control() after GetHubDescriptor request being processed. move all debounce operation to usb port's runtime resume callback(). Add did_runtime_put in the struct usb_port to call pm_runtime_get/put(portdev) paired. using pm_runtime_get/put(portdev) to allow or prohibit device to be power off inside of pm qos request in the kernel side. Change since v2: Correct some link breaks. Add did_runtime_put in the usb_disconnect() before calling pm_runtime_put(portdev). Provide two seperate functions usb_device_allow_power_off() and usb_device_prevent_power_off() instead of just one. Change since v3: Set did_runtime_put to false in usb_disconnect() when its value is true Add comment about not enable port runtime pm if fail to expose port's pm qos. and call pm_runtime_set_active(portdev) unconditionally. rename usb_device_allow_prevent_power_off with usb_device_control_power_off Modify be power off to be powered off Expose dev_pm_qos_flags() symbol in order to ensure usb core can compile as module. Resend v4: make patch PM/Qos: Expose dev_pm_qos_flags symbol as first patch to avoid compilation error during git bisect correct some comments. Change since v5: use EXPORT_SYMBOL_GPL to export dev_pm_qos_flags(). correct some unnecessary link breaks. Add CONFIG_USB_SUSPEND check around usb_port_runtime_resume() and usb_port_runtime_suspend() This patchset is based on usb-next tree commit 6e30d7cba usb: Add driver/usb/core/(port.c,hub.h) files and the patch usb: fix compilation error and warning of driver/usb/core/port.c on arm and blackfin http://marc.info/?l=linux-usbm=135860593115173w=2 This patchset is to add usb port power off mechanism and merge with patchset usb: expose DeviceRemovable to user space via sysfs attribute. Patchset usb: expose DeviceRemovable to user space via sysfs attribute. http://marc.info/?l=linux-usbm=135279430410171w=2 with some link break corrects The main discussion about usb port power off mechanism is in the following link: http://marc.info/?l=linux-usbm=134818340017208w=2 PM/Qos: Expose dev_pm_qos_flags symbol USB: Set usb port's DeviceRemovable according acpi information usb: Add portX/connect_type attribute to expose usb port's connect type usb: Create link files between child device and usb port device. usb: Register usb port's acpi power resources usb: add runtime pm support for usb port device usb: add usb port auto power off mechanism usb: expose usb port's pm qos flags to user space usb: add usb_device_allow_power_off() and usb_device_prevent_power_off() function. usb: enable usb port device's async suspend. -- 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
