When building an external module, the ezusb_* functions are not defined if we haven't loaded any built'in module that use them (whiteheat, keyspan, ...). This patch allow to build those functions even if we only have selected the usbserial generic driver.

This patch (as1030b) moves a del_timer_sync() call outside the scope of a spinlock, where it could cause a deadlock, and adds a new del_timer_sync() call for the new IAA watchdog timer (it was omitted by mistake).

This has some bugfixes for the EHCI driver's ISO transfer scanning logic. It was leaving ITDs and SITDs on the schedule too long, for a few different reasons, which caused trouble. (a) Look at all microframes for high speed transfers, not just the ones we expect to have finished. This way transfers ending mid-frame will complete without needing another IRQ. This also minimizes bogus scheduling underruns (e.g. EL2NSYNC). (b) When we encounter an ISO transfer (either speed, but this hits mostly at full speed) that's not yet been completed, immediately stop scanning; we've caught up to the hardware, no matter what other indications might say. (c) Always clean up ITDs (for high speed transfers) when the HC is no longer running. I'm not sure whether the last one has been observed before, but both the others have been reported with "real world" audio and video code.

Small updates to the EHCI driver's ISO support: - Get rid of the Kconfig option for full speed ISO. It may not be perfect yet, but it hasn't appeared to be dangerous and pretty much every configuration wants it. - Instead of two places to disable an empty periodic schedule after an ISO transfer completes, just have one. - After the periodic schedule is disabled, we can short-circuit the schedule scan ... it can't possibly have more work to do. Assuming a typical config with split iso enabled, the only change in behavior should be almost unobservable: quicker termination of periodic scans when the schedule gets emptied.

In the EHCI driver, itd->usecs[8] is used in periodic_usecs(), indexed by uframe. For an ITD's unused uframes it is 0, else it contains the same value as itd->stream->usecs. To check if an ITD's uframe is used, we can instead test itd->hw_transaction[uframe]: if used, it will be nonzero no matter what endianess is used. This patch replaces those two uses, eliminates itd->usecs[], and saves eight bytes from each ITD.

Various small at91_udc cleanups: - Use generic GPIO calls, not older platform-specific ones - Use gpio_request()/gpio_free() - Use VERBOSE_DEBUG convention, not older VERBOSE - Fix sparse complaint about parameter type (changed to gfp_t) - Add missing newline to some rarely-seen debug messages - Fix some old cleanup bugs on probe() fault paths Also add a mechanism whereby rm9200 gpios can drive the D+ pullup through an inverting transistor, based on a patch from Steve Birtles. Most UDC drivers supporting a GPIO based pullup should probably have such an option, but testing it requries such a board in hand!

Update the ohci-at91 bus glue to start understanding about the per-port power switch GPIOs it's given (on the sam9263-ek and potentially other boards). For the moment this just claims them and forces them active (assuming active-low power enables) whenever the HCD is loaded. The assumption is still that board setup configures the GPIOs. Using gpio_request() tracks actual usage and guards against conflict. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch exports two statistics to userspace: /sys/bus/usb/device/.../power/connected_duration /sys/bus/usb/device/.../power/active_duration connected_duration is the total time (in msec) that the device has been connected. active_duration is the total time the device has not been suspended. With these two statistics, tools like PowerTOP can calculate the percentage time that a device is active, i.e. not suspended or auto-suspended. Users can also use the active_duration to check if a device is actually autosuspended. Currently, they can set power/level to auto and power/autosuspend to a positive timeout, but there's no way to know from userspace if a device was actually autosuspended without looking at the dmesg output. These statistics will be useful in creating an automated userspace script to test autosuspend for USB devices.

[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.

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.
