[PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors There are more devices similar to the Olimex JTAG adaptor, in that the first port of the FT2232C is used for JTAG, and only the second port is available as UART. I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the OOCDlink device. I've also updated the KERN_INFO message sent to userspace to remove the word 'olimex' and an extra '\n' that was causing an empty line in dmesg.

Don't pass NULL into termios functions when calling them internally Remove all the crap which then checks for NULL which can't occur now Clear CMSPAR as it is not supported Report the baud rate back to the caller properly (See FIXME someone with the docs) Signed-off-by:

Fix a small glitch noted by Yannick Cote. There is no endpoint number six, so if a (broken) host wrongly tried to change or read status of that endpoint, the driver could access reserved register space. Signed-off-by:

Kernel bugzilla entry #9569 reports a potential OOPS in some code supporting the integrated root hub TT support used on ARC/TDI derived cores. (This seems to have been a longstanding issue.) This patch cleans up usage of urb->dev->tt to avoid that potential oops and also fixes some overly long lines. Signed-off-by:

This adds a workaround for an issue reported with ISO transfers on some EHCI controllers, most recently with VIA KT800 and PS3 EHCI silicon. The issue is that the silicon doesn't necessarily seem to be done using ISO DMA descriptors (itd, sitd) when it marks them inactive. (One theory is that the ill-defined mechanism where hardware caches periodic transfer descriptors isn't invalidating their state...) With such silicon, quick re-use of those descriptors makes trouble. Waiting until the next frame seems to be a sufficient workaround. This patch ensures that the relevant descriptors aren't available for immediate re-use. It does so by not recycling them until after issuing the completion callback which would reuse them by enqueueing an URB and thus (re)allocating ISO DMA descriptors. Signed-off-by:

Without this fix, the pl2303 usb-serial adapter would not suspend properly unless it had been opened first. A pl2303 type_1 chip will still break if the system is hibernated while the RS-232 connector is powered by another system. This was broken before, and a reset resume does not fix it. All other suspend and autosuspend scenarios work with ATEN pl2303 adaptors with HX and type_1 chips. Signed-off-by:

This patch (as1028) was mostly written by David Brownell; I made only a few changes (extra log info and a small bug fix -- which might account for why David's version had to be reverted). It adds a new watchdog timer to the ehci-hcd driver to be used exclusively for detecting lost or missing IAA notifications. Previously a shared timer had been used, which may have led to some problems as reported by Christian Hoffmann. Signed-off-by:

This patch (as1022b) adds stub methods for suspend and resume to the usbfs driver. There isn't much they can do since there's no way to inform a user task about the events. But it's important to have the stubs, because an upcoming change to usbcore will automatically unbind drivers that don't have those methods when a suspend occurs. Signed-off-by:

This patch (as1023) updates the code in usb_reset_composite_device(): Some local variable declarations are moved to inner loops. The interface locks are not acquired. This isn't necessary any more; its only reason was to prevent an interface from being suspended or resumed during the reset. But now interface power management is controlled by the USB device lock, not by the interface lock. The check for whether the interface is registered is removed. There doesn't seem to be any reason for checking; a driver for a non-registered interface deserves to be informed of device resets just as much as any other. Signed-off-by:

For as long as I've known about it, the USBDEVFS_CONNECT ioctl hasn't done what it's supposed to. The current code reprobes _all_ the unbound USB interfaces; this patch (as1021) makes it reprobe only the interface for which it was called. Signed-off-by:

The OHCI driver's IRQ handler, while processing a WDH interrupt, masks and unmasks it. I believe this is both broken (the write may still be posted during the donelist processing it's trying to safeguard) and useless as this IRQ may not be reissued until it's acked (unless this legacy code is an uncommented workaround for some chip erratum).

This patch (as1017) makes dummy_hcd behave more like the other USB peripheral controller drivers by no longer registering its gadget driver on the platform bus. Doing that has always been a mistake, since a usb_gadget_driver isn't a platform_driver. Instead the gadget driver is left unregistered in sysfs. Signed-off-by:

I'm having problem with oopses when rebooting, if I modprobe g_serial and rmmod g_serial and do a reboot I get an oops in device_shutdown(). The reason seems to be that usb_gadget_unregister_driver() doesn't do enough cleanup. With this at91_udc patch I don't get the oops. Signed-off-by:
