This is a simple "CDC Subset" (and MCCI "SAFE") function driver, extracted from the all-in-one Ethernet gadget driver. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Abstract the peripheral side Ethernet-over-USB link layer code from the all-in-one Ethernet gadget driver into a component that can be called by various functions, so the various flavors can be split apart and selectively reused. A notable difference from the approach taken with the serial link layer code (beyond talking to NET not TTY) is that because of the initialization requirements, this only supports one network link. (And one set of Ethernet link addresses.) That is, each configuration may have only one instance of a network function. This doesn't change behavior; the current code has that same restriction. If you want multiple logical links, that can easily be done using network layer tools.

Split out the generic serial support into a "function driver". This closely mimics the ACM support, but with a MUCH simpler control model. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Split out CDC ACM parts of "gadget serial" to a "function driver". Some key structural differences from the previous ACM support, shared with with the generic serial function (next patch): - As a function driver, it can be combined with other functions. One gadget configuration could offer both serial and network links, as an example. - One serial port can be exposed in multiple configurations; the /dev/ttyGS0 node could be exposed regardless of which config the host selected. - One configuration can expose multiple serial ports, such as ttyGS0, ttyGS1, ttyGS2, and ttyGS3. This code should be a lot easier to understand than the previous all-in-one-big-file version of the driver.

Update Gadget Zero to use the more modular versions of the loopback and source/sink configuration drivers which build on the new gadget framework code. The core code is a LOT simpler, and it should be much easier now to understand how the parts fit together. The conversion is an overall source shrink in terms of this gadget, since it uses more midlayer support. However, it's an overall increase in object size because there's less sharing between the two configurations (improves code clarity) and because the midlayer is a bit more functional than this driver actually needs.

Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue, and remove all the orignal tangled-up code. Update the documentation accordingly. This is a net object code shrink and cleanup; it should make it a lot easier to see how the TTY glue should accomodate updates to the TTY layer, be bugfixed, etc. Notable behavior changes include: it can now support getty even when there's no USB connection; it fits properly into the mdev/udev world; and RX handling is better (throttling works, and low latency). Configurations with scripts setting up the /dev/ttygserial device node (with "experimental" major number) may want to change that to be a symlink pointing to the /dev/ttyGS0 file, as a migration aid; else, just switch entirely over to mdev/udev.

The pxa2xx_udc.c driver is renamed to pxa25x_udc.c (the platform driver name changes from pxa2xx-udc to pxa25x-udc) and the platform driver name of pxa27x_udc.c is fixed to pxa27x-udc. pxa_device_udc in devices.c is split into pxa25x and pxa27x flavors and the pxa27x_device_udc is enabled in pxa27x.c.

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. Signed-off-by: Craig W.

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.

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.

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!
