Adds pxa27x udc driver to support USB peripherals on pxa27x chips.
The driver is compatible with: Gadget Zero, the File Storage
gadget, and the Ethernet gadget (only in CDC subset mode).
The driver can't properly support multiple interfaces, because
of hardware bugs without possible workaround. That means no
RNDIS support from g_ether, and no CDC ACM support in g_serial.

G_PRINTER: Adds a USB printer gadget driver for use in printer firmware.
This adds a USB printer gadget driver for use in printer firmware.
The printer gadget channels data between the USB host and a userspace
program driving the print engine. The user space program reads and
writes the device file /dev/g_printer to receive or send printer data.
It can use ioctl calls to the device file to get or set printer status.

This is a driver for the Atmel USBA UDC which can be found integrated
on AT32AP700x AVR32 processors. For hardware documentation, please see
the AT32AP7000 data sheet:
http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf
This is a dual speed controller (connects at high or full speed).
The driver supports up to 7 control, bulk, interrupt and isochronous
endpoints with some constraints. Bulk, interrupt and isochronous
transfers are driven by DMA.

Driver for the AMD5536 UDC, as found in the AMD Geode CS5536 (southbridge).
This is a high speed DMA-capable controller, which can also be used in
OTG configurations (which are not supported by this patch).

Although the other USB driver directories got taught how use Kconfig
and the Makefile to enable the debugging messages enabled by -DDEBUG,
the gadget stack was overlooked.
This patch remedies that omission, but doesn't update any drivers to
remove previous idiosyncracies in this area ... other than the RNDIS
code, which defined its own DEBUG() macro in a broken way.

This patch adds the support for the Usb Device Controller on Samsung
S3C24xx SoCs. This driver passes all tests from testusb (including #13)
and has been tested on S3C2410, S3C24212, and S3C2440 SoCs.

I would like to submit Renesas M66592 udc driver.
The M66592 is Renesas USB 2.0 peripheral controller.
This controller supports USB high-speed.
The driver has been tested Gadget Zero, Ethernet Gadget,
File-backed Storage Gadget, and passed usbtest script.

Freescale high-speed USB SOC can be found on some Freescale processors
among different architectures. It supports both host and device functions.
This driver adds its device support for Linux USB Gadget layer.
It is tested on MPC8349 and MPC8313, but should work on other platforms
with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note
that this driver doesn't yet include OTG support.

This driver is glue between the USB gadget interface
and the ALSA MIDI interface. It allows us to appear
as a MIDI Streaming device to a host system on the
other end of a USB cable.
This includes linux/usb/audio.h and linux/usb/midi.h
containing definitions from the relevant USB specifications
for USB audio and USB MIDI devices.
The following changes have been made since the first RFC
posting:
* Bug fixes to endpoint handling.
* Workaround for USB_REQ_SET_CONFIGURATION handling,
not understood yet.
* Added SND and SND_RAWMIDI dependencies in Kconfig.
* Moved usb_audio.h and usb_midi.h to usb/*.h
* Added module parameters for ALSA card index and id.
* Added module parameters for USB descriptor IDs and strings.
* Removed some unneeded stuff inherited from zero.c, more to go.
* Provide DECLARE_* macros for the variable-length structs.
* Use kmalloc instead of usb_ep_alloc_buffer.
* Limit source to 80 columns.
* Return actual error code instead of -ENOMEM in a few places.

This adds support for the USB peripheral controller on AT91
(rm9200, eventually also sam9261 or uClinux) platforms.
More SOC support for Linux-USB ... an uncomplicated pure PIO driver.
It'd be worth using this as a model, if you're starting a driver
for some other peripheral controller.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
