      [PATCH] add usb transceiver set_suspend() method · 4e67185a
      Juha Yrj?l? authored
      When a USB device is put into suspend mode, the current drawn from VBUS
      has to be less than 500 uA. Some transceivers need to be put into a
      special power-saving mode to accomplish this, and won't have a separate
      OTG driver handling that.
      
      This adds a suspend method to the "otg_transceiver" struct -- misnamed,
      it's not only for OTG -- and calls it from the OMAP UDC driver.

      [PATCH] Fix hcd->state assignments in uhci-hcd · f37be9b9
      Alan Stern authored
      This patch (as581) changes the assignments to hcd->state in the uhci-hcd
      driver.  It fixes part of bugzilla entry #5227.  The problem was revealed
      by David's large suite of USB suspend/resume patches; this patch should go
      to Linus at the same time those do.

      [PATCH] omap_udc dma off-by-one fix · cb97c5c9
      David Brownell authored
      The change to make DMA work two bytes at a time omitted an important
      tweak that affects the file_storage gadget:  it needs to recognize when
      the host writes an odd number of bytes.  (The network layer ignores
      such extra bytes.)
      
      This patch resolves that issue by checking the relevant bit and adjusting
      the rx byte count, so that for example a legal 13 byte request doesn't
      morph into an illegal 14 byte one any more.

      [PATCH] UHCI: Improve handling of iso TDs · b81d3436
      Alan Stern authored
      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_suspend · 0c0382e3
      Alan Stern authored
      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 code · bb200f6e
      Alan Stern authored
      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.

      [PATCH] USB Storage: HP8200: Another device type detection fix · a8798533
      Daniel Drake authored
      There appears to be one more case where the HP8200 CD writer devices are
      detected as flash readers - when the USB cable is replugged after use, with
      the power cable still connected.
      
      Oddly enough, the identify device command appears to 'fall through' when the
      devices are in this state, the status register reading exactly the same opcode
      as the command (0xA1) that was just executed.
      
      I think it's safe to label this behaviour as specific to HP8200 devices, I
      can't get the flash devices to respond like this.
      
      This patch should solve the last of the HP8200 issues which have cropped up
      recently.

      [PATCH] USB: usb_bulk_message() handles interrupts endpoints · d09d36a9
      Alan Stern authored
      Because there is no bulk_interrupt_message() routine and no
      USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the
      usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt
      transfers as well as bulk transfers.
      
      This patch (as567) formalizes this practice and adds code to
      usb_bulk_message() for detecting when the target is really an interrupt
      endpoint.  If it is, the routine submits an interrupt URB (using the
      default interval) instead of a bulk URB.  In theory this should help HCDs
      that don't like it when people try to mix transfer types, queuing both
      periodic and non-periodic types for the same endpoint.
      
      Not fully tested -- I don't have any programs that use USBDEVFS_BULK for
      interrupt transfers -- but it compiles okay and normal bulk messages work
      as well as before.

        - 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.

      [PATCH] OHCI PM updates · f197b2c5
      David Brownell authored
      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?).

      [PATCH] usbcore PCI glue updates for PM · 5f827ea3
      David Brownell authored
      This updates the PCI glue to address the new and simplified usbcore suspend
      semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because
      hcd->hub_suspend() will always be called.
      
        - Removes now-unneeded recursion support
      
        - Go back to ignoring faults reported by the wakeup calls; we expect them
          to fail sometimes, and that's just fine.
      
      The PCI HCDs will need simple changes to catch up to this, like being able
      to ignore the setting of CONFIG_USB_SUSPEND.

      [PATCH] root hub updates (greater half) · f3f3253d
      David Brownell authored
      This patch associates hub suspend and resume logic (including for root hubs)
      with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying
      two troublesome versions of suspend logic into just one.  It'll be easier to
      keep things right from now on.
      
        - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of
          only when USB_SUSPEND is enabled:
           * Those root hub methods are now called from hub suspend/resume;
             no more skipping between layers during device suspend/resume;
           * It now handles cases allowed by sysfs or autosuspended root hubs,
             by forcing the hub interface to resume too.
      
        - All devices, including virtual root hubs, now get the same treatment
          on their resume paths ... including re-activating all their interfaces.
      
      Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and
      updates the Kconfig to match the new definition of USB_SUSPEND:  it provides
      (a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream
      from any device configuration which supports it.
      
      This calls for minor followup patches for most HCDs (and their PCI glue).

      [PATCH] root hub changes (lesser half) · 979d5199
      David Brownell authored
      This patch collects various small updates related to root hubs, to shrink
      later patches which build on them.
      
        - For root hub suspend/resume support:
           * Make the existing usb_hcd_resume_root_hub() routine respect pmcore
             locking, exporting and using the dpm_runtime_resume() method.
           * Add a new usb_hcd_suspend_root_hub() to pair with that routine.
             (Essential to make OHCI autosuspend behave again...)
           * HC_SUSPENDED by itself only refers to the root hub's downstream ports.
             So let HCDs see root hub URBs unless the parent device is suspended.
      
        - Remove an assertion we no longer need (and now, also don't want).
      
        - Generic suspend/resume updates to work better with swsusp.
           * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to
             use it breaks the swsusp snapshots it's supposed to help (sigh).
           * On resume, mark devices as resumed right away, but then
             do nothing else if the device is marked NOTATTACHED.
      
      These changes shouldn't be very noticable by themselves.

      [PATCH] all HCDs provide root hub suspend/resume methods · 9293677a
      David Brownell authored
      This cleans up a small recent FIXME, ensuring that all the HCDs provide
      root hub suspend/resume methods.  It also wraps the calls to those root
      suspend routines just like on the PCI "USB_SUSPEND not defined" cases,
      so non-PCI bus glue won't be as tempted to behave very differently.
      
      Several of the SOC based OHCI drivers forgot to list those methods;
      the patch also adds those missing declarations.

      [PATCH] one less word in struct device · e9b7bd4e
      David Brownell authored
      This saves a word from "struct device" ... there's a refcounting mechanism
      stub that's rather ineffective (the values are never even tested!), which
      can safely be deleted.  With this patch it uses normal device refcounting,
      so any potential users of the pm_parent mechanism will be more correct.
      (That mechanism is actually unusable for now though; it does nothing.)

      This patch (as563) splits the physical and logical framelist arrays in
      uhci-hcd into two separate pieces.  This will allow slightly better memory
      utilization, since each piece is no larger than a single page whereas
      before the whole thing was a little bigger than two pages.  It also allows
      the logical array to be allocated in non-DMA-coherent memory.

      [PATCH] USB: UHCI: Remove unused fields and unneeded tests for NULL · 8b4cd421
      Alan Stern authored
      This patch (as562) removes from the uhci-hcd driver a few unused fields
      and some unnecessary tests against NULL and assignments to NULL.  In fact
      it wasn't until fairly recently that the tests became unnecessary.
      Before last winter it was possible that the driver's stop() routine would
      get called even if the start() routine returned an error, but now that
      can't happen.  Hence there's no longer any need to check for partial
      initialization.
