* usb: gadget zero style fixups (mostly whitespace)David Brownell2008-05-021-193/+172
| | | | | | | | | | | | | | | Minor updates to "Gadget Zero". - Primarily these are whitespace updates to address the fact that since this was written, Documentation/CodingStyle was changed to disapprove of parts of the original coding style. - Update a few comments that weren't quite correct, notably mentioning the "autoresume" module parameter.

* usb serial gadget: CDC ACM fixesDavid Brownell2008-05-021-17/+73
| | | | | | | | | | | | | | | | Based on a patch from <Aurel.Thomi@ruag.com>, this makes the CDC-ACM support in the serial gadget handle the SET_LINE_CODING and SET_CONTROL_LINE_STATE requests ... which should improve interop with at least MS-Windows "usbser.sys" if not some other ACM host drivers. It also adds a few REVISIT comments where this code plays a bit loose with the CDC ACM spec. If this were used to hook up to a real RS232 or modem link, those places would need a bit of work.

* usb: pxa27x_udc driverRobert Jarzmik2008-05-025-4/+2916
| | | | | | | | | | | | | | | | 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.

This is what it should have done all along, because the dynamically-allocated structures have a release method in the driver core and are therefore immune to being released after the module has been unloaded.

The AT91CAP9 uses the same UDPHS IP as the AVR32 and the AT91SAM9RL. The only differences between the AVR32 and the AT91 version of the device are in the enable/disable and suspend/wakeup sequences: the AT91 version needs to toggle the USB bias and pulldown explicitly.

* USB: device DMA support on OMAP2Kyungmin Park2008-02-011-22/+49
| | | | | | | | | | | | | | | | | The current omap udc dosen't support the DMA mode and it has some problem at setup time on OMAP2 with previous patch file. I found that the code assumes bulk out required the big data transfer. But MODE SELECT(6) sent the only 24 bytes. it makes a problem. So I implement the small packets handling for it. It is tested with both linux and windows.
