This patch is a pretty mechanical change.  The usage model doesn't change

incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so

This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers.  When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.

In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops).  This requires extra code, but the total delay
time is reduced.

There are also a few additional minor cleanups.

An undocumented "feature" in the OMAP3 EHCI controller causes
suspended ports to be taken out of suspend when the USBCMD.Run/Stop
bit is cleared (this bit is normally cleared when ehci_bus_suspend
is called).

This "feature" breaks suspend-resume if the root-hub is allowed
to suspend. (The controller thinks it is in resume, and the PHY
thinks it is still in suspend).

There is an undocumented register bit that can be used to disable
this feature and restore normal behavior. Set this bit so
suspend-resume can work normally.

There were some reports[1] of isp1760 USB driver malfunctioning
with high speed devices, noticed on Blackfin and PowerPC targets.
These reports indicated that the original Philips 'pehcd'[2]
driver worked fine.

We've noticed the same issue with an ARM RealView platform. This
happens under load (with only some mass storage devices, not all,
just as in another report[3]):

  error bit is set in DW3
  error bit is set in DW3
  error bit is set in DW3
  usb 1-1.2: device descriptor read/64, error -32

It appears that the 'pehcd' driver checks the X bit only if the
transaction is halted (H bit), otherwise the error is so far
insignificant.

The ISP176x chips were modeled after EHCI, and EHCI spec says
(thanks to Alan Stern for pointing out):

"Transaction errors cause the status field to be updated to reflect
 the type of error, but the transaction continues to be retried until
 the Active bit is set to 0.  When the error counter reaches 0, the
 Halt bit is set and the Active bit is cleared."

So, just as the original Philips driver, isp1760 must report the
error only if the transaction error and the halt bits are set.

Bulk endpoint streams were added in the USB 3.0 specification.  Streams
allow a device driver to overload a bulk endpoint so that multiple
transfers can be queued at once.

The device then decides which transfer it wants to work on first, and can
queue part of a transfer before it switches to a new stream.  All this
switching is invisible to the device driver, which just gets a completion
for the URB.  Drivers that use streams must be able to handle URBs
completing in a different order than they were submitted to the endpoint.

This requires adding new API to set up xHCI data structures to support
multiple queues ("stream rings") per endpoint.  Drivers will allocate a
number of stream IDs before enqueueing URBs to the bulk endpoints of the
device, and free the stream IDs in their disconnect function.  See
Documentation/usb/bulk-streams.txt for details.

The new mass storage device class, USB Attached SCSI Protocol (UASP), uses
these streams API.

Much of the xHCI driver code assumes that endpoints only have one ring.
Now an endpoint can have one ring per enabled stream ID, so correct that
assumption.  Use functions that translate the stream_id field in the URB
or the DMA address of a TRB into the correct stream ring.

Correct the polling loop to print out all enabled stream rings.  Make the
URB cancellation routine find the correct stream ring if the URB has
stream_id set.  Make sure the URB enqueueing routine does the same.  Also
correct the code that handles stalled/halted endpoints.

Check that commands and registers that can take stream IDs handle them
properly.  That includes ringing an endpoint doorbell, resetting a
stalled/halted endpoint, and setting a transfer ring dequeue pointer
(since that command can set the dequeue pointer in a stream context or an
endpoint context).

Correct the transfer event handler to translate a TRB DMA address into the
stream ring it was enqueued to.  Make the code to allocate and prepare TD
structures adds the TD to the right td_list for the stream ring.  Make
sure the code to give the first TRB in a TD to the hardware manipulates
the correct stream ring.

When an endpoint stalls, store the stream ID of the stream ring that
stalled in the xhci_virt_ep structure.  Use that instead of the stream ID
in the URB, since an URB may be re-used after it is given back after a
non-control endpoint stall.

Add support for allocating streams for USB 3.0 bulk endpoints.  See
Documentation/usb/bulk-streams.txt for more information about how and why
you would use streams.

When an endpoint has streams enabled, instead of having one ring where all
transfers are enqueued to the hardware, it has several rings.  The ring
dequeue pointer in the endpoint context is changed to point to a "Stream
Context Array".  This is basically an array of pointers to transfer rings,
one for each stream ID that the driver wants to use.

The Stream Context Array size must be a power of two, and host controllers
can place a limit on the size of the array (4 to 2^16 entries).  These
two facts make calculating the size of the Stream Context Array and the
number of entries actually used by the driver a bit tricky.

Besides the Stream Context Array and rings for all the stream IDs, we need
one more data structure.  The xHCI hardware will not tell us which stream
ID a transfer event was for, but it will give us the slot ID, endpoint
index, and physical address for the TRB that caused the event.  For every
endpoint on a device, add a radix tree to map physical TRB addresses to
virtual segments within a stream ring.

Keep track of whether an endpoint is transitioning to using streams, and
don't enqueue any URBs while that's taking place.  Refuse to transition an
endpoint to streams if there are already URBs enqueued for that endpoint.

We need to make sure that freeing streams does not fail, since a driver's
disconnect() function may attempt to do this, and it cannot fail.
Pre-allocate the command structure used to issue the Configure Endpoint
command, and reserve space on the command ring for each stream endpoint.
This may be a bit overkill, but it is permissible for the driver to
allocate all streams in one call and free them in multiple calls.  (It is
not advised, however, since it is a waste of resources and time.)

Even with the memory and ring room pre-allocated, freeing streams can
still fail because the xHC rejects the configure endpoint command.  It is
valid (by the xHCI 0.96 spec) to return a "Bandwidth Error" or a "Resource
Error" for a configure endpoint command.  We should never see a Bandwidth
Error, since bulk endpoints do not effect the reserved bandwidth.  The
host controller can still return a Resource Error, but it's improbable
since the xHC would be going from a more resource-intensive configuration
(streams) to a less resource-intensive configuration (no streams).

If the xHC returns a Resource Error, the endpoint will be stuck with
streams and will be unusable for drivers.  It's an unavoidable consequence
of broken host controller hardware.

This patch (as1368) fixes a rather obscure bug in usbmon: When tracing
URBs sent by the scatter-gather library, it accesses the data buffers
while they are still mapped for DMA.

The solution is to move the mapping and unmapping out of the s-g
library and into the usual place in hcd.c.  This requires the addition
of new URB flag bits to describe the kind of mapping needed, since we
have to call dma_map_sg() if the HCD supports native scatter-gather
operation and dma_map_page() if it doesn't.  The nice thing about
having the new flags is that they simplify the testing for unmapping.

The patch removes the only caller of usb_buffer_[un]map_sg(), so those
functions are #if'ed out.  A later patch will remove them entirely.

As a result of this change, urb->sg will be set in situations where
it wasn't set previously.  Hence the xhci and whci drivers are
adjusted to test urb->num_sgs instead, which retains its original
meaning and is nonzero only when the HCD has to handle a scatterlist.

Finally, even when a submission error occurs we don't want to hand
URBs to usbmon before they are unmapped.  The submission path is
rearranged so that map_urb_for_dma() is called only for non-root-hub
URBs and unmap_urb_for_dma() is called immediately after a submission
error.  This simplifies the error handling.

The length of the scatter gather list a driver can enqueue is limited by
the bus' sg_tablesize to 62 entries.  Each entry will be described by at
least one transfer request block (TRB).  If the entry's buffer crosses a
64KB boundary, then that entry will have to be described by two or more
TRBs.  So even if the USB device driver respects sg_tablesize, the whole
scatter list may take more than 62 TRBs to describe, and won't fit on
the ring.

Don't assume that an empty ring means there is enough room on the
transfer ring.  The old code would unconditionally queue this too-large
transfer, and over write the beginning of the transfer.  This would mean
the cycle bit was unchanged in those overwritten transfers, causing the
hardware to think it didn't own the TRBs, and the host would seem to
hang.

Now drivers may see submit_urb() fail with -ENOMEM if the transfers are
too big to fit on the ring.

When the USB core installs a new interface, it unconditionally clears the
halts on all the endpoints on the new interface.  Usually the xHCI host
needs to know when an endpoint is reset, so it can change its internal
endpoint state.  In this case, it doesn't care, because the endpoints were
never halted in the first place.

To avoid issuing a redundant Reset Endpoint command, the xHCI driver looks
at xhci_virt_ep->stopped_td to determine if the endpoint was actually
halted.  However, the functions that handle the stall never set that
variable to NULL after it dealt with the stall.  So if an endpoint stalled
and a Reset Endpoint command completed, and then the class driver tried to
install a new alternate setting, the xHCI driver would access the old
xhci_virt_ep->stopped_td pointer.  A similar problem occurs if the
endpoint has been stopped to cancel a transfer.
