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. ]

This patch (as1075) changes dummy-hcd to dynamically allocate its
platform_device structures, using the core platform_device_alloc()
interface.  This is what it should have done all along, because the
dynamically-allocated structures have a release method in the driver
core and are therefore immune to being released after the module has
been unloaded.

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.

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.

The .suspend and .resume method pointers in struct usb_hcd have not
been fully understood by host-controller driver writers.  They are
meant for use with PCI controllers; other platform-specific drivers
generally should not refer to them.

To try and clarify matters, this patch (as1065) renames those methods
to .pci_suspend and .pci_resume.  It eliminates corresponding dead code
and bogus references in the ohci-ssb and u132-hcd drivers.

This fixes bugs in blocking IO calls. When the poll() entry point
is called receive transfers will be setup if they have not already
been. Another bug fix is that the poll() entry point now checks the
current receive buffer for data when reporting if any data had been
received. A memory leak was fixed that could have occurred when a

I have got a cypress usb-ide bridge and I would like to tune or monitor
my disk with tools like hdparm, hddtemp or smartctl.

My controller support a way to send raw ATA command to the disk with
something call atacb (see
http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf).

Atacb support can be added for each application, but there is some disadvantages :
- all application need to be patched
- A race is possible if there other accesses, because the emulation can
be split in 2 atacb scsi transactions. One for sending the command, one
for reading the register (if ck_cond is set). 

I have implemented the emulation in usb-storage with a special proto_handler,
and an unsual entry.
