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.

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.

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.

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.

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?).

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.

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).

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.

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.

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.

This gets rid of some inconsistently duplicated logic to resume interfaces.

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).

This patch removes some recursion in the CONFIG_USB_SUSPEND logic, which
suspended children (of devices or hubs) that weren't already suspended.
When it sees such cases, suspend now just fails cleanly.
That logic was not needed during system-wide sleep state transitions; and
given the current notions of how to manage selective suspend transitions,
we don't want it there either. Where it was particularly handy was coping
with various limitations of the sysfs "echo -n N > power/state" support.
(These include assuming that "N" is always meaningful to the driver; and
that drivers can only transition to state N from state zero.)

This updates the handling of power state for USB interfaces.
- Formalizes an existing invariant: interface "power state" is a boolean:
ON when I/O is allowed, and FREEZE otherwise. It does so by defining
some inlined helpers, then using them.
- Adds a useful invariant: the only interfaces marked active are those
bound to non-suspended drivers. Later patches build on this invariant.
- Simplifies the interface driver API (and removes some error paths) by
removing the requirement that they record power state changes during
suspend and resume callbacks. Now usbcore does that.
A few drivers were simplified to address that last change.

This moves the PCI quirk handling for USB host controllers from the
PCI directory to the USB directory. Follow-on patches will need to:
(a) merge these copies with the originals in the HCD reset methods.
they don't wholly agree, despite doing the very same thing; and
(b) eventually change it so "usb-handoff" is the default, to help
get more robust USB/BIOS/input/... interactions.

This patch enables direct kernel support for the Artemis
and ATIK astronomical based USB CCD cameras.
Since all communications with this camera are done via an
FTDI 245BM chip, it was only needed to specify the
ProductID and VendorID of all three devices.
In what tests are concerned, data was transfered from and
to the FTDI at the chips Top speed (360KB/s).

This tweaks the EHCI reboot notifier to also halt the EHCI controller, and
makes that halt code force IRQs off. Both should always have been done.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. 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.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

The previous patch adding the ability to nest struct class_device
changed the paramaters to the call class_device_create(). This patch
fixes up all in-kernel users of the function.
