* [USB]: Make early handoff a final fixup instead of a header one.David S. Miller2005-11-041-1/+1
| | | | | | | | At header fixup time, it is not yet legal to ioremap() PCI device registers, yet that is what this quirk code needs to do. Signed-off-by: David S. Miller <davem@davemloft.net>
* Don't touch USB controller IO registers when they are disabledLinus Torvalds2005-10-311-0/+23
| | | | | | | | | The USB "handoff" code is an early PCI quirk to make sure we own the USB controller (as opposed to the BIOS/SMM). But if the controller isn't even enabled yet, don't try to access it. Acked-by: Paul Mackerras <paulus@samba.org> (who had an alternate patch) Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | [PATCH] fix missing includesTim Schmielau2005-10-303-0/+6
|/ | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] USB: Always do usb-handoffAlan Stern2005-10-281-43/+3
| | | | | | | | | | | | This revised patch (as586b) makes usb-handoff permanently true and no longer a kernel boot parameter. It also removes the piix3_usb quirk code; that was nothing more than an early version of the USB handoff code (written at a time when Intel's PIIX3 was about the only motherboard with USB support).

| | | | | | | | | | This patch (as581) changes the assignments to hcd->state in the uhci-hcd driver. It fixes part of bugzilla entry #5227.

* [PATCH] UHCI: Improve handling of iso TDsAlan Stern2005-10-281-13/+26
| | | | | | | | | | | | | | | | | | | | | The uhci-hcd driver is fairly lax about the way it handles isochronous transfers. This patch (as579) improves it in three respects: TDs for a new URB aren't added to the schedule until all of them have been allocated. This way there's no risk of the controller executing some of them when an allocation fails. TDs for an unlinked URB are removed from the schedule as soon as the URB is unlinked, rather than waiting until the URB is given back. This way there's no risk of the controller still executing a TD after the URB completes. The urb->error_count values are now reported correctly. Although since they aren't used in any drivers except for debug messages in the system log, probably nobody cares.

* [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern2005-10-2814-41/+41
| | | | | | | | | | | | | | | | This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

* [PATCH] UHCI: unify BIOS handoff and driver reset codeAlan Stern2005-10-282-112/+106
| | | | | | | | | | | | | | This patch (as574) updates the PCI BIOS usb-handoff code for UHCI controllers, making it work like the reset routines in uhci-hcd. This allows uhci-hcd to drop its own routines in favor of the new ones (code-sharing). Once the patch is merged we can turn the usb-handoff option on permanently, as far as UHCI is concerned. OHCI and EHCI may still have some issues. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ... This patch makes it do so by: - Resetting the controller after kicking BIOS off, matching the normal "chip in hardware reset" startup mode; - Reporting any BIOS that borks this simple handoff; it's likely got a few other surprises for us too. - Ignoring that handoff on HPPA; The diagnostic string is mostly shared with EHCI, saving a few bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the OHCI root hub suspend logic: - Uses new usbcore root hub calls to make autosuspend work again: * Uses a newish usbcore root hub wakeup mechanism, making requests to khubd not keventd. * Uses an even newer sibling suspend hook. - Expect someone always made usbcore call ohci_hub_suspend() before bus glue fires; and that ohci_hub_resume() is only called after that bus glue ran. Previously, only CONFIG_USB_SUSPEND promised those things. (Includes updates to PCI and OMAP bus glue.) - Handle a not-noticed-before special case during resume from one of the swsusp snapshots when using "usb-handoff": the controller isn't left in RESET state. (A bug to fix in the usb-handoff code...) Also cleans up a minor debug printk glitch, and switches an mdelay over to an msleep (how did that stick around for so long?).

In fact it wasn't until fairly recently that the tests became unnecessary.

* [PATCH] remove usb_suspend_device() parameterDavid Brownell2005-10-283-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the extra usb_suspend_device() parameter. The original reason to pass that parameter was so that this routine could suspend any active children. A previous patch removed that functionality ... leaving no reason to pass the parameter. A close analogy is pci_set_power_state, which doesn't need a pm_message_t either. On the internal code path that comes through the driver model, the parameter is now used to distinguish cases where USB devices need to "freeze" but not suspend. It also checks for an error case that's accessible through sysfs: attempting to suspend a device before its interfaces (or for hubs, ports).

However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work.

The fix attached was tested in 2 ways: (a) it fixed failing initialization of a flash drive with an embedded hub; (b) the fix was tested with 'usbtest' against a modified g_zero driver (on top of net2280), which generated short bulk IN transfers of various lengths including multiples and non-multiples of max_packet_length.

| | | | | | | | | | | | | | | | | | | | | | | | | One change may improve some S1 or S3 resume cases, and the other seems mostly to explain some strange state "lsusb" would show. Two fixes: - On resume, don't think about resuming any unpowered port, or resetting any port with OWNER set to the OHCI/UHCI companion. This will make some S1 and S3 resume scenarios work better. - PORT_CSC was not being cleared correctly in ehci_hub_status_data. This was visible at least through current versions of "lsusb", and might have caused some other hub related strangeness. The fix addresses all three write-to-clear bits, using the same approach that UHCI happens to use: a mask of bits that are cleared in most writes to that port status register.

| * [PATCH] USB: remove include of asm/usb.h in ohci-ppc-soc.cDale Farnsworth2005-09-081-18/+4
| | | | | | | | | | | | | | | | | | | | | | ohci-ppc-soc.c provides for a platform-specific callback mechanism for when the HC is successfully probed or removed. It turned out that none of the 3 platforms using it need this facility. Also the required include/asm-ppc/usb.h has never been accepted. This patch removes the callback feature and the include of <asm/usb.h>. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * [PATCH] USB: Switch isp116x-hcd over to root hub interruptOlav Kongas2005-09-081-13/+22
| | | | | | | | | | | | | | | | | | Switch isp116x-hcd over from root hub polling to interrupt. This change closes also a race that was present with the old polling scheme: status polling could happen in a time window, where root hub status bits were not stable.

| * [PATCH] USB: isp116x-hcd: remove clock() and reset()Olav Kongas2005-09-081-28/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes support for user-provided platform-specific hardware reset and clock starting/stopping functions. Hardware reset was needed earlier as getting the software reset working was tricky due to the lack of documentation. Recently, a number of people using isp116x have said the software reset is working for them. I haven't heard of anybody using the clock starting/stopping.
