First set of fixes for v4.8-rc cycle. Again, dwc3 is the most active driver with over 60% of this pull request touching it. The most important fixes are related to scatterlist usage with dwc3. Before this pull request, we were increment request->actual multiple times and this would result in request->actual being larger than request->length. Also, if a we received a short packet midway through processing a scatterlist, we were not clearning HWO bit as we should. Other than the large dwc3 scatterlist fixes, we have a new Device ID for Intel's Kabylake silicon. Other drivers, such as fsl_qe_udc and renesas udc, also got a few minor fixes. Details are in shortlog. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXrGw7AAoJEIaOsuA1yqREVv8QAKs+UEW+M2hnX1jolG4525YY 0fEYHVuH8K+PSzhG0aPr3vWG3GHBn37in4l0Ey5x5dyBxkFN2LQfnPkBWMYQeFAS fBwh1o+V+Xec7DHUDqgexb10kOKVI7U2H3Ob9VV9BMYKU1D5SgRduG569UDPzWIJ bXyHYOiTEwdubu+eXNAZA05nFSoZinHQ/m/4alaIfoOGJo6sHs7mLuVaAdp4g+OA vD6UgOTFSuSB+rDbYLhxSc9kVwRFQKAEe5u/YuI6Puxpsnsu1D5S5t/KPty1DTUV UZS63O3L3VcdGe54hew7iPg/UKGcUCaOw/HUJlro+d/jxrz48AqgAlQr3ZGxhdWJ LDDkWJJhNJXdBs7TmrrZfC+qhLRhvAXVasf/TFaXAsejHU5KeyiDCp0UU/LnqYlD YIAVnxL6er2Sn3jI6KJQ4Ek8uufpAZZ3gFWZ60Ka6AXXYVdu5PTnaca+3J0eyVjZ F4kWWyR3wFSJ1zmWvTJsnuww77cLoUu7sPg+w4dvIoG/x1yGg+JBuBJzq1VyF307 XDHtM+134Y4XVbvz5wIySLOmXnLPCb1F6Gp67GjuoBOMjL086JvFlbut2/bJs7Nj 6RVHRJUECaTRUQz5dUEYYwoFnjQXgWv7vEn4QD/507jm4krcxhuxaDgtK47yKjXS DGjMIGO0b3yK8rvqqoWM =7VYA -----END PGP SIGNATURE----- Merge tag 'fixes-for-v4.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.8-rc1 First set of fixes for v4.8-rc cycle.

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 ("hub_wq"). 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.
