Over two years ago, the Linux USB developers stated that they believed there was no way to create a USB kernel driver that was not under the GPL. This patch moves the USB apis to enforce that decision. There are no known closed source USB drivers in the wild, so this patch should cause no problems. Signed-off-by: -

Turns out that a company is out there using the vendor id of 0x0000 in the wild, so use a real vendor/product id for the root hubs. Now that the Linux Foundation has a real vendor id, we use that, and the first product id: 0x1d6b is the vendor id of the Linux Foundation 0x0001 is the product id for Linux 1.1 root hubs 0x0002 is the product id for Linux 2.0 root hubs The usb.ids file has already been updated with these values.

While most isochronous endpoints have short polling intervals, the EHCI driver won't necessarily handle larger ones correctly. This patch switches to use a "u16" to represent those periods, not a u8, since it can always work: the largest expressible period is 2^15 units ... not the previous too-short limit of 128 frames (full or low speeds) or microframes (high speed, 32 frames). This bug is essentially theoretical, since the few ISO endpoints I've seen which don't use one transfer per frame are high speed ones using more than that (including high bandwidth, 24 KB/msec).

Some of the "EHCI ports reset forever" problems may be explained by code paths which wrongly flagged resets as complete. This removes two such paths; the ehci_hub_status_data() path should be the only one to have an effect, since it was already properly flagged on the other path.

usb: ohci-sm501 driver V2 This patch adds sm501 ohci support. It's all very straightforward with the exception of dma_declare_coherent_memory() and HCD_LOCAL_MEM. Together they are used to ensure that usb data is allocated using dma_alloc_coherent(), and that only valid dma memory is used to allocate from. This driver is a platform device, and the mfd driver sm501.c is already creating one usb host controller instance per sm501. Signed-off-by:

usb: dma bounce buffer support V4 This patch adds dma bounce buffer support to the usb core. These buffers can be enabled with the HCD_LOCAL_MEM flag, and they make sure that all data passed to the host controller is allocated using dma_alloc_coherent(). Signed-off-by:

these drivers abused intfdata in close() as flags for binding. That races with reprobing of those devices. This patch fixes that by using the flag and the locks introduced with the patch against mos7720. Signed-off-by:

this driver uses usb_get_intfdata() == NULL as a test for disconnect(). You must not do that as this races with probe(). By the time you test your erstwhile interface may already be somebody else's interface. This fixes the close() method of cypress_m8 to use the recently introduced flag and use locking against disconnect() where required in close(). Signed-off-by:

This fixes a problem where the mos7720 driver will make io to a device from which it has been logically disconnected. It does so by introducing a flag by which the generic usb serial code can signal the subdrivers their disconnection and appropriate locking. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
