Kay Sievers f4fce61d41 usb host: fix platform driver hotplug/coldplug
Since 43cc71eed1, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable USB HCDs,
to allow re-enable auto loading.

Stelian Pop 16a45bc82e atmel_usba_udc: Add support for AT91CAP9 UDPHS
This patch is part of the series adding support for the USB High
Speed Device Port on the AT91CAP9 system on chip. The AT91CAP9
uses the same UDPHS IP as the AVR32 and the AT91SAM9RL.

The only differences between the AVR32 and the AT91 version of the
device are in the enable/disable and suspend/wakeup sequences: the
AT91 version needs to toggle the USB bias and pulldown explicitly.

Stelian Pop 8d855317fc atmel_usba_udc: move endpoint declarations into platform data.
The atmel_usba_udc driver is being used by several platforms and arches
(avr32 and at91 ATM), and each platform may have different endpoint
settings.

Clark Rawlins 822470537d USB: Allow initialization of broken keyspan serial adapters.
Fixes the keyspan driver after the addition of additional
checking of driver requirements introduced in usb-serial.c
commit 063a2da8f0.  The initialization
of the keyspan usb_serial_driver structs were not initializing the
num_interrupt_out field and the additional checking was rejecting
the end point so the driver wouldn't finish initializing.

This commit initializes the fields to NUM_DONT_CARE.
It works for the keyspan USA-49WG and doesn't break the USA-19HS
which are the two keyspan devices I have to test with.

Brad Sawatzky d04863e9e6 USB: serial: fix regression in Visor/Palm OS module for kernels >= 2.6.24
Fixes a bug/inconsistency revealed by the additional sanity checking in
   commit 063a2da8f0
introduced in the original 2.6.24 branch.

The Handspring Visor / PalmOS 4 device structure defines .num_bulk_out=2
but the usb-serial probe returns num_bulk_out=3, triggering the check in
the above commit and forcing a bail out when the device (a Garmin iQue in
my case) attempts to connect.  The patch bumps the expected number of
endpoints to 3.

FWIW, this patch will probably solve the following kernel bug report for
Treo users (identical symptoms, different model PalmOS units):

Robert Spanton 1bfd6693cd USB: serial: ti_usb_3410_5052: Correct TUSB3410 endpoint requirements.
The changes introduced in commit
063a2da8f0 changed the semantics of the
num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out
entries of the usb_serial_driver struct to be the number of endpoints
the device has when probed.

This patch changes the ti_1port_device usb_serial_driver struct to
reflect this change.  The single port devices only have 1
bulk_out endpoint in their initial configuration, and so this patch
changes the number of other types to NUM_DONT_CARE.

The same change probably needs doing to the ti_2port_device struct,
but I don't have a two port device at hand.

Rene Herman 055b93c9e3 USB: ehci: stop vt6212 bus hogging
The VIA VT6212 defaults to only waiting 1us between passes over EHCI's
async ring, which hammers PCI badly ... and by preventing other devices
from accessing the bus, causes problems like drops in IDE throughput,
a problem that's been bugging users of those chips for several years.

A (partial) datasheet for this chip eventually turned up, letting us
see how to make it use a VIA-specific register to switch over to the
the normal 10us value instead, as suggested by the EHCI specification
Solution noted by Lev A. Melnikovsky.

It's not clear whether this register exists on other VIA chips; we
know that it's ineffective on the vt8235.  So this patch only applies
to chips that seem to be incarnations of the (discrete) vt6212.

David Brownell e82cc1288f USB: fix ehci unlink regressions
The recent EHCI driver update to split the IAA watchdog timer out from
the other timers made several things work better, but not everything;
and it created a couple new issues in bugzilla.  Ergo this patch:

  - Handle a should-be-rare SMP race between the watchdog firing
    and (very late) IAA interrupts;

  - Remove a shouldn't-have-been-added WARN_ON() test;

  - Guard against one observed OOPS;

  - If this watchdog fires during clean HC shutdown, it should act
    as a NOP instead of interfering with the shutdown sequence;

  - Guard against silicon errata hypothesized by some vendors:
      * IAA status latch broken, but IAAD cleared OK;
      * IAAD wasn't cleared when IAA status got reported;

The WARN_ON is in bugzilla as 10168; the OOPS as 10078; these are
both regressions.

Alan Stern 6d512a80c2 usb-storage: update earlier scatter-gather bug fix
This patch (as1037) makes a small update to the earlier as1035 patch.
The minimum-length computation shouldn't be done in
usb_stor_access_xfer_buf(), since that routine can be called multiple
times for a single transfer.  It should be done in
usb_stor_set_xfer_buf() instead, which gets called only once.

The way it is now isn't really _wrong_, but it isn't really _right_
either.  Moving the statement will be an improvement.

Misha Zhilin b5f7a0ec11 USB: ehci: handle large bulk URBs correctly (again)
USB: ehci: Fixes completion for multi-qtd URB the short read case

When use of urb->status in the EHCI driver was reworked last August
(commit 14c04c0f88), a bug was inserted
in the handling of early completion for bulk transactions that need
more than one qTD (e.g. more than 20KB in one URB).

This patch resolves that problem by ensuring that the early completion
status is preserved until the URB is handed back to its submitter,
instead of resetting it after each qTD.

Rafael J. Wysocki 3a2d5b7001 PM: Introduce PM_EVENT_HIBERNATE callback state
During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.

But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.

For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.

These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

The only reason for adding them originally was to get an ancient
ZIP-100 drive to work.  But since this device has only a single LUN,
we don't need to send it a Get-Max-LUN request at all.  Adding an
unusual_devs entry for the ZIP-100 with the SINGLE_LUN flag set will
cause this step to be skipped.

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.

David Brownell c06d4dcf50 usb: ehci should use u16 for isochronous intervals
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).

David Brownell cd4cdc93ce usb: ehci, remove false clear-reset path
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.  (Issue noted by Minhyoung Kim <a9a9@lge.com>.)

Magnus Damm f54aab6ebc usb: ohci-sm501 driver
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.

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.
