We have here the usual set of cleanups for the MUSB driver; a big set of patches converting platform_device_del() and platform_device_put() into platform_device_unregister(). Another big set was applied converting to module_platform_driver() macro in order to reduce some boilerplate code from all glue layers. Other than that, we had a series fixing one known silicon errata where we couldn't read a few registers. In order to fix that we're now using shadow variables for reads and only writing to the registers which are known to break functionality when read. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJQnWnTAAoJEIaOsuA1yqREsb8P/2fYBTfwJSzlr4Gw7CWIedw1 6l0VsHRBPr7cnUFmbkxdVAcDbuqfDrtEZoYSxF97DoDmqKqM4JXcGsozLn62J4pL E0jscaojx1ZbELEoWWTY4Sr7KBIz5SPYnZhQFj2S3oXWtDvQe+3NyGU6uJxwTjzD A57xpSAJmruQE+8hPL2e1/rPR+I9ZmaebhpQ2cyNTFWu/tv+Q7VtpvjtreD1C/fZ 0IVlyz6r/2OXB4C//xWfJ2BRPa6wRHAu/BpH5HU0P84hPi7hshtjKHjWUZFkuDHy JsBArA2LGJN2Jc62H9tiKaD28kHWNm99P7XPkCnPRY7bfAINZ6SwDxYCrQ9QKpNq ExLLhdJA4rhVQATRlwczluFNK1rTVSxJQFEcK/hkopK8wK/B+mgWqDu4OZDDhowu u8/pPNM9gJe1/NNVfSigJ9f/h0wb25Ua+V7MyrmCOuQq1tdVELYfHCj+VhjqAIud YzBLsGTnrto7TYYV2wuc6iiHW0nJ0zrBOiSfsUjLiGoB0dH224MqCvezwUREqyob fy25JmyCVjlxZ5wkfjJ9UlFuruWJHJf2zVr04xfdxaUY9eUk1rmEmhNR9mAlfnQG 3fJC580fVgHVceucOP2knsnXAzGjy/jr+xiFzOU9lE8NopO46qtbmBm5CwcW0STX L9IJq7SA2KhuVpGpQkwf =tr2i -----END PGP SIGNATURE----- Merge tag 'musb-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB musb merge from Felipe: "usb: musb: patches for v3.8 merge window We have here the usual set of cleanups for the MUSB driver; a big set of patches converting platform_device_del() and platform_device_put() into platform_device_unregister().

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.
