Linus Torvalds ba01a87e37 Merge branch 'usb-target-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull usb-gadget scsi-target merge from Nicholas Bellinger:
 "As promised, here is the pull request for Sebastian's usb-gadget
  target UASP / BOT driver for v3.5-rc1.  This code has been in
  linux-next for a number of weeks, and is now ready for an initial
  merge.

  This fabric uses the target framework to provide a usb gadget device.
  This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk
  Only Transfers (BOT or BBB).  BOT is the primary interface, UAS is the
  alternative interface.

  Note this series is dependent upon a single target core patch for
  adding se_cmd->unknown_data_length in target-pending/for-next, that
  got merged in the parent.

  Kudos to Sebastian for making this driver happen so easily, and for
  his patches to improve usb-core and target core along the way to his
  goal.  Also thanks to Felipe + Greg-KH for their help in getting this
  driver ready for mainline."

To understand all the Linux-USB framework, you'll use these resources:

    * This source code.  This is necessarily an evolving work, and
      includes kerneldoc that should help you get a current overview.
      ("make pdfdocs", and then look at "usb.pdf" for host side and
      "gadget.pdf" for peripheral side.)  Also, Documentation/usb has
      more information.

    * The USB 2.0 specification (from www.usb.org), with supplements
      such as those for USB OTG and the various device classes.
      The USB specification has a good overview chapter, and USB
      peripherals conform to the widely known "Chapter 9".

    * Chip specifications for USB controllers.  Examples include
      host controllers (on PCs, servers, and more); peripheral
      controllers (in devices with Linux firmware, like printers or
      cell phones); and hard-wired peripherals like Ethernet adapters.

    * Specifications for other protocols implemented by USB peripheral
      functions.  Some are vendor-specific; others are vendor-neutral
      but just standardized outside of the www.usb.org team.

Here is a list of what each subdirectory here is, and what is contained in
them.

core/		- This is for the core USB host code, including the
		  usbfs files and the hub class driver ("khubd").

host/		- This is for USB host controller drivers.  This
		  includes UHCI, OHCI, EHCI, and others that might
		  be used with more specialized "embedded" systems.

gadget/		- This is for USB peripheral controller drivers and
		  the various gadget drivers which talk to them.


Individual USB driver directories.  A new driver should be added to the
first subdirectory in the list below that it fits into.

image/		- This is for still image drivers, like scanners or
		  digital cameras.
../input/	- This is for any driver that uses the input subsystem,
		  like keyboard, mice, touchscreens, tablets, etc.
../media/	- This is for multimedia drivers, like video cameras,
		  radios, and any other drivers that talk to the v4l
		  subsystem.
../net/		- This is for network drivers.
serial/		- This is for USB to serial drivers.
storage/	- This is for USB mass-storage drivers.
class/		- This is for all USB device drivers that do not fit
		  into any of the above categories, and work for a range
		  of USB Class specified devices. 
misc/		- This is for all USB device drivers that do not fit
		  into any of the above categories.
