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." * 'usb-target-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: usb-gadget: Initial merge of target module for UASP + BOT |

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.
