As part of reorienting uhci-hcd away from URBs and toward endpoint queues, this patch (as625) eliminates the driver's main list of URBs. The list wsa used mainly in checking for URB completions; now the driver goes through the list of active endpoints and checks the members of the queues. As a side effect, I had to remove the code that looks for FSBR timeouts. For now, FSBR will remain on so long as any URBs on a full-speed control or bulk queue request it, even if the queue isn't advancing. A later patch can add more intelligent handling. This isn't a huge drawback; it's pretty rare for an URB to get stuck for more than a fraction of a second. (And it will help the people trying to use those insane HP USB devices.) Signed-off-by:

This patch (as624) fixes a hardware race in uhci-hcd by adding a dummy TD to the end of each endpoint's queue. Without the dummy the host controller will effectively turn off the queue when it reaches the end, which happens asynchronously. This leads to a potential problem when new transfer descriptors are added to the end of the queue; they may never get used. With a dummy TD present the controller never turns off the queue; instead it just stops at the dummy and leaves the queue on but inactive. When new TDs are added to the end of the queue, the first new one gets written over the dummy. Thus there's never any question about whether the queue is running or needs to be restarted.

This patch (as623) changes the uhci-hcd driver to make it use one QH per device endpoint, instead of a QH per URB as it does now. Numerous areas of the code are affected by this. For example, the distinction between "queued" URBs and non-"queued" URBs no longer exists; all URBs belong to a queue and some just happen to be at the queue's head. Signed-off-by:

This patch adds a second linksys vendor-id (077b) and the product id of the pegasus based adapter USBVPN1 http://www1.linksys.com/Products/product.asp?prid=3D543&scid=3D30 Furthermore it replaces all LINKSYS_GPIO_RESET with DEFAULT_GPIO_RESET as both are declared like this: #define DEFAULT_GPIO_RESET 0x24 #define LINKSYS_GPIO_RESET 0x24 This is misleading and confusing. The check is now done via the VENDOR_ID in pegasus.c: if (usb_dev_id[pegasus->dev_index].vendor == VENDOR_LINKSYS Signed-off-by:

This patch (as628c) adds error handling to the USB HID core. When an error is reported for an interrupt URB, the driver will do delayed retries, at increasing intervals, for up to one second. If that doesn't work, it will try to reset the device. Testing by users has shown that both the retries and the resets end up getting used. Signed-off-by:

This makes usbcore use the driver model wakeup flags for host controllers and for their root hubs. Since previous patches have removed all users of the HCD flags they replace, this converts the last users of those flags. Signed-off-by:

This makes OHCI use the driver model wakeup control bits for its root hub (e.g. disable on amd756, because of chip erratum) and for the controller itself. It no longer uses the hcd glue bits with those roles, and depends on the previous patch making the root hub available earlier. Note that on most platforms (boot code properly setting the RWC bit) this gives a partial workaround for the way PCI isn't currently flagging devices that support PME# signals. (Because of odd PCI init sequencing on PPC.) That's because many OHCI controllers support "legacy PCI PM" ... without involving any PCI PM capability. USB wakeup from STR, if it works on your system, may still involve tweaking things by hand in /proc/acpi/wakeup. Signed-off-by:

Make the HCD initialization sequence more sane ... notably, setting up root hubs before HCDs are asked to do their one-time init. Among other things, that lets the HCDs do custom root hub init along with all the other one-time initialization done in the (now misnamed) reset() method. This also copies the controller wakeup flags into the root hub; it's done a bit later than would be ideal, but that'll be necessary until the PCI code initializes them correctly. (The PCI patch breaks on PPC due to how it sequences PCI initialization.) Signed-off-by:

This adds declarations for three USB peripheral controllers: - Two high speed USB cores that can be licensed from Mentor Graphics to be integrated into silicon: * "musbhsfc" is for peripherals only, as found in for example the IBM/AMCC 44EP processors. * "musbhdrc" is OTG-capable (dual role), and is found in various products including OMAP 2430 and the new DaVinci SOCs. The "musbh" standing for "Mentor USB Highspeed", the rest standing for "Function Controller" or "Dual Role Controller" (OTG-capable). - The full speed controller on the FreeScale MPC8272. Adding these definitions just allows gadget driver code to handle any controller-specific logic; controller drivers are quite separate.

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. Signed-off-by:

This adds support for OHCI on AT91rm9200 based boards. Possibly of interest here is the way this uses <linux/clk.h> to gate clocks on/off during system pm state transitions. That's typical for non-PCI systems. Some can go further; Mini-A host side connectors enable ID-pin sensing. From: Andrew Victor <andrew@sanpeople.com> Signed-off-by:

This patch modifies the behavior of the EHCI driver in an unlink path that seems to be causing various issues on some systems. Those problems have included issues with disconnection, driver unbinding, and similar cases where urb unlinking would just not work right. This patch should help avoid those problems by not turning off the async (control/bulk) schedule until it's not expecting an "async advance" IRQ, which comes from the processing passing the schedule head. Whether the driver attempts to do such things is dependent on system timings, so many folk would never have seen these problems. Signed-off-by:

On the MPC834x processors the multiport host (MPH) EHCI controller has an erratum in which the port number in the queue head expects to be 0..N-1 instead of 1..N. If we are on one of these chips we subtract one from the port number before putting it into the queue head. Signed-off-by:

Adding a Host Mode USB driver for the Freescale 83xx. This driver supports both the Dual-Role (DR) controller and the Multi-Port-Host (MPH) controller present in the Freescale MPC8349. It has been tested with the MPC8349CDS reference system. This driver depends on platform support code for setting up the pins on the device package in a manner appropriate for the board in use. Note that this patch requires selecting the EHCI controller option under the USB Host menu. Signed-off-by:

This patch replaces the split ISO raw_mask calculation code in the iso_stream_init() function that computed incorrect numbers of high speed transactions for both input and output transfers. In the output case, it added a superfluous start-split transaction for all maxmimum packet sizes that are a multiple of 188. In the input case, it forgot to add complete-split transactions for all microframes covered by the full speed transaction, and the additional complete-split transaction needed for the case when full speed data starts arriving near the end of a microframe. These changes don't affect the lack of full speed bandwidth, but at least it removes the MMF errors that the HC raised with some input streams. Signed-off-by:

This teaches the EHCI driver about a quirk seen in older NForce2 chips, adding a workaround to ignore selective suspend requests. Bus-wide (so-called "global") suspend still works, as does USB wakeup of a root hub that's globally suspended. There's still a hole in this support though. Strictly speaking, this should _fail_ selective suspend requests, rather than ignoring them, since doing it this way means that devices which should be able to issue remote wakeup are not going to be able to do that. For now, we'll just live with that problem ... since usbcore expects to do selective suspend on the way towards a full bus suspend, and usbcore needs to be able to do full bus suspend. Signed-off-by:
