Subject: [PATCH V4 0/8] usb: make usb port a real device and provide control of port's power to usr space
Date: Thu, 28 Jun 2012 15:31:34 +0800 [thread overview]
Message-ID: <1340868702-1894-1-git-send-email-tianyu.lan@intel.com> (raw)
This patchset merged two following patchsets and make usb port a real device.
[PATCH V3 1/4] usb: add struct usb_hub_port to store
[PATCH V3 2/4] usb: move struct usb_device->children
[PATCH V3 3/4] usb/acpi: add the support of usb hub
[PATCH V3 4/4] usb/acpi: add usb check for the connection
[PATCH 1/3] xhci: Add clear PORT_POWER feature process in the
[PATCH 2/3] USB/ACPI: Add usb port's acpi power control in the xhci
[PATCH 3/3] usb : Add sysfs files to control usb port's power
This patchset is to provide usb port power off mechanism. Add two
attributes "portX/control" and "portX/state" for each ports
under the usb hub interface sysfs directory.
"portX/control" has two options
"on" - port power must be on.
"off" - port power must be off.
"portX/state" reports usb port's power state
"on" - power on
"off" - power off
"error" - can't get power state
[PATCH V4 1/8] usb: convert port_owners type from void * to struct
[PATCH V4 2/8] usb: make usb port a real device
[PATCH V4 3/8] usb: move children to struct usb_port
[PATCH V4 4/8] usb/acpi : rebinding usb with acpi since usb port
