Merge tag 'usb-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH:
"Here is the big USB and PHY driver updates for 4.11-rc1.
Nothing major, just the normal amount of churn in the usb gadget and
dwc and xhci controllers, new device ids, new phy drivers, a new
usb-serial driver, and a few other minor changes in different USB
drivers.
All have been in linux-next for a long time with no reported issues"

+Broadcom USB3 phy binding for northstar plus SoC
+The USB3 phy is internal to the SoC and is accessed using mdio interface.

+Required mdio bus properties:
+- reg: Should be 0x0 for SoC internal USB3 phy
+- #address-cells: must be 1
+- #size-cells: must be 0
+
+Required USB3 PHY properties:
+- compatible: should be "brcm,nsp-usb3-phy"
+- reg: USB3 Phy address on SoC internal MDIO bus and it should be 0x10.
+- usb3-ctrl-syscon: handler of syscon node defining physical address
+ of usb3 control register.
+- #phy-cells: must be 0
+
+Required usb3 control properties:
+- compatible: should be "brcm,nsp-usb3-ctrl"

- Thanks Guys :)

+[Overview]
+USB/IP protocol allows to pass USB device from server to client over the
+network. Server is a machine which provides (shares) a USB device. Client is
+a machine which uses USB device provided by server over the network.
+The USB device may be either physical device connected to a server or
+software entity created on a server using USB gadget subsystem.
+Whole project consists of four parts:
+
+ - usbip-vhci
+ A client side kernel module which provides a virtual USB Host Controller
+ and allows to import a USB device from a remote machine.
+
+ - usbip-host (stub driver)
+ A server side module which provides a USB device driver which can be
+ bound to a physical USB device to make it exportable.
+
+ - usbip-vudc
+ A server side module which provides a virtual USB Device Controller and allows
+ to export a USB device created using USB Gadget Subsystem.
+
+ - usbip-utils
+ A set of userspace tools used to handle connection and management.
+ Used on both sides.
[Requirements]
- USB/IP device drivers
- Found in the staging directory of the Linux kernel.
+ Found in the drivers/usb/usbip/ directory of the Linux kernel tree.
