aff6d18f95 USB: fix compile problems in ehci-hcd
This patch (as1072) fixes some recently-introduced compile problems
that show up in ehci-hcd when CONFIG_PM is turned off.

	PORT_WAKE_BITS needs to be defined always.

	ehci_port_power() is called during initialization by all the
	EHCI variants other than the PCI version, in which it is
	"defined but not used".  So add a call to it.

4f6676274f USB: ehci: qh_completions cleanup and bugfix
Simplify processing of completed qtds, and correct handling of short
reads, by removing two state variables:

 - "qtd_status" wasn't needed.  The current URB's status is either
   OK (-EINPROGRESS) or some fault status.  Once a fault appears,
   the queue halts and any later QTDs are immediately removed, so
   no temporary status is needed.  (Or for typical short reads,
   it's not treated as a fault, so no queue halt is needed.)

 - "do_status" was erroneous.  Because of how the queue is set up,
   short control reads can (and should!) be treated like full size
   reads, and cleaned up the usual way.  The status stage will be
   executed transparently, and usbcore handles the choice of whether
   to report this status as unexected.
 
The "do_status" problem caused a rather perplexing timing-dependent
problem with usbtest case 10.  Sometimes it would make the controller
skip a dozen transactions while (wrongly) trying to clean up after a
short transfer.  Fortunately, removing a dcache contention issue made
this become trivial to reproduce (on one test rig), so enough clues
finally presented themselves ... I think this has been around for a
very long time, but was worsened by recent urb->status changes.

c6dbf554bc USB: cdc-acm: signedness fix
Fix bogus assignment of "unsigned char *" to "char *":  preserve
unsignedness.  These values are used directly as descriptor lengths
when iterating through the buffer, so this *could* cause oddness
that potentially includes oopsing.  (IMO not likely, except as
part of a malicious device...)

Fix the bogus warning in CDC ACM which highlighted this problem
(by showing a negative descriptor type).  It uses the undesirable
legacy err() for something that's not even an error; switch to
use dev_dbg, and show descriptor types in hex notation to match
the convention for such codes.

e872154921 USB: don't explicitly reenable root-hub status interrupts
This patch (as1069b) changes the way OHCI root-hub status-change
interrupts are enabled.  Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub.  This approach turns out to be subject to races, resulting
in unnecessary polling.

The patch does away with the method entirely.  Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present.  This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

5f47493cdf USB: OHCI: turn off RD when remote wakeup is disabled
This patch (as1068b) disables the RD interrupt flag when an OHCI root
hub is suspended with remote wakeup disabled.  Although the spec
clearly states that this flag permits the controller to issue an
interrupt when a resume request from downstream is detected and not
when a local status change occurs, some controllers mistakenly use it
for both types of event.

58a97ffeb2 USB: HCDs use the do_remote_wakeup flag
When a USB device is suspended, whether or not it is enabled for
remote wakeup depends on the device_may_wakeup() setting.  The setting
is then saved in the do_remote_wakeup flag.

Later on, however, the device_may_wakeup() value can change because of
user activity.  So when testing whether a suspended device is or
should be enabled for remote wakeup, we should always test
do_remote_wakeup instead of device_may_wakeup().  This patch (as1076)
makes that change for root hubs in several places.

The patch also adjusts uhci-hcd so that when an autostopped controller
is suspended, the remote wakeup setting agrees with the value recorded
in the root hub's do_remote_wakeup flag.

And the patch adjusts ehci-hcd so that wakeup events on selectively
suspended ports (i.e., the bus itself isn't suspended) don't turn on
the PME# wakeup signal.

21da84a893 USB: ehci shutdown refactored
This patch refactors some shutdown code so it can be shared between
ehci_stop() and ehci_shutdown().

This also fixes a couple potential bugs:
 - ehci_shutdown() was not locking ehci->lock before halting the HC.
 - ehci_shutdown() didn't disable the watchdog and IAA timers.
 - ehci_stop() was resetting the host controller when it may have been
   running, which the EHCI spec says "may result in undefined behavior".

ehci_stop() was calling port_power() to turn off the ports, which waited
20ms after applying the port change.  The msleep was for the case where
the HC might take 20ms to turn the ports on; since we're shutting them
off, we can avoid the msleep and just use ehci_turn_off_ports().

ehci_stop() doesn't need to clear the intr_enable register or revert
ownership of the companion controllers to the BIOS, because the host
controller reset should have done that.  There might be a buggy host
controller that doesn't follow the reset rules, but for now we assume
it's redundant code and remove it.

[ A subsequent patch will cancel the timers later ... this version
carries forward existing bugs where timers could get re-armed
after they're canceled. ]

61a5c65789 USB: rework sysfs removal of interface files
Removing an interface's sysfs files before unregistering the interface
doesn't work properly, because usb_unbind_interface() will reinstall
altsetting 0 and thereby create new sysfs files.  This patch (as1074)
removes the files after the unregistration is finished.  It's not
quite as clean, but at least it works.

Also, there's no need to check if an interface has been registered
before removing its sysfs files.  If it hasn't been registered then
the files won't have been created, so usb_remove_sysfs_intf_files()
will simply do nothing.

43bbb7e015 USB: OHCI: host-controller resumes leave root hub suspended
Drivers in the ohci-hcd family should perform certain tasks whenever
their controller device is resumed.  These include checking for loss
of power during suspend, turning on port power, and enabling interrupt
requests.

Until now these jobs have been carried out when the root hub is
resumed, not when the controller is.  Many drivers work around the
resulting awkwardness by automatically resuming their root hub
whenever the controller is resumed.  But this is wasteful and
unnecessary.

To simplify the situation, this patch (as1066) adds a new core
routine, ohci_finish_controller_resume(), which can be used by all the
OHCI-variant drivers.  They can call the new routine instead of
resuming their root hubs.  And ohci-pci.c can call it instead of using
its own special-purpose handler.

and bogus references in the ohci-ssb and u132-hcd drivers.

* 20.  With this patch I get the maximum througput from my linux system
with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both)

I also deleted the flag URB_NO_FSBR for the writeurbs, because this
makes my full speed devices significant slower.

528e4c12a7 USB: Remove EXPERIMENTAL designation from USB MDC800 support.
Since support for the USB Mustek MDC800 Digital Camera has apparently
been around since the beginning of the git repository, it's safe to
assume it's no longer experimental.

Based on a recent discussion on the Linux USB mailing list, remove the
designation of EXPERIMENTAL from some USB gadget entries, and tag some
of them as DEVELOPMENT.
