finally getting rid of the old ->start()/->stop() methods in favor of the better and improved ->udc_start()/->udc_stop(). There were surprisingly quite a few users left, but all of them have been converted. f_mass_storage removed some dead code, which is always great ;-) There's also a big cleanup to the gadget framework from Sebastian which gets us a lot closer to having only function drivers in kernel and move over to configfs-based binding. Other than these, there's the usual set of cleanups: s3c UDCs are moving over to devm_regulator_bulk_get() API, at91_udc removed an unnecessary check for work_pending() before scheduling and there's the removal of an unused variable from uac2_pcm_trigger(). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJRAqbFAAoJEIaOsuA1yqREkXsQAInuD5h4OE4gMQSFWJbYY+it BWN3JAIxm5NTKD9cez7d0vQ45v+9qDygBpHP4lsGGjhI0tkOr+nQ/g/sfSi3xbHM HQ6/z7Y68pNz9k57ans9NfIt0AuIsHE79tlOx3g+QVvryLHmQSAUzk9ru0VUHw4D rSI3Czk3yCA4UnRITxJYpsnmEAZw/M7DwyMANqdNFzZaruMB77phsCWGIM2O0h1T lw3sgcBoFcvYodWCzi90NWMA8FccQLMxBg6G+7ViaqGvAPqSuYwNTHJxxUwPHdbI o28gQY7gkxZY9MwbnFZ+7jSbpcmzRpYtpgBflubf4iAkv+197lG6I5XyVgfdEZSF AF3qi7asrXX/jjFoXASpmphBdCazz6G9bTmtdT3RpV3MKC6fnS1tXImBgreveIWh sjhPQCleCCZI2+KLpVOujk3kUVHc9aJ5zbqcNLu03Ux1qqqK0VlZ9bahtip6HQ8H GYhEdOmgIAe83CcJeWBdWAoz2c7fzEEvCj+TxxbyB7nE8TRsOYooKrBcfEM1plVy qWcXULlhTdD4aWpQLanL8XSamKFvyDk+lEn4803of0eaVpE9gUxKi0fwD+j6UOMV iBa7mEx5zIym7gJI4+SlvXIn8fPHfcHGX4BPLASd+G4ndkLIPc2wAb/KqVyIUCXt I5K8UNYb0DiuQtxKXg8R =PCP4 -----END PGP SIGNATURE----- Merge tag 'gadget-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: gadget: patches for v3.9 merge window finally getting rid of the old ->start()/->stop() methods in favor of the better and improved ->udc_start()/->udc_stop().

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.
