The usb_device structure contains an array of usb_device "children".
This array is only valid if the usb_device is a hub, so it makes no
sense to store it there. Instead, store the usb_device child
in its parent usb_port structure.
Since usb_port is an internal USB core structure, add a new function to
get the USB device child, usb_hub_find_child(). Add a new macro,
usb_hub_get_each_child(), to iterate over all the children attached to a
particular USB hub.
Remove the printing the USB children array pointer from the usb-ip
driver, since it's really not necessary.

The Intel desktop boards DH77EB and DH77DF have a hardware issue that
can be worked around by BIOS. If the USB ports are switched to xHCI on
shutdown, the xHCI host will send a spurious interrupt, which will wake
the system. Some BIOS will work around this, but not all.
The bug can be avoided if the USB ports are switched back to EHCI on
shutdown. The Intel Windows driver switches the ports back to EHCI, so
change the Linux xHCI driver to do the same.
Unfortunately, we can't tell the two effected boards apart from other
working motherboards, because the vendors will change the DMI strings
for the DH77EB and DH77DF boards to their own custom names. One example
is Compulab's mini-desktop, the Intense-PC. Instead, key off the
Panther Point xHCI host PCI vendor and device ID, and switch the ports
over for all PPT xHCI hosts.
The only impact this will have on non-effected boards is to add a couple
hundred milliseconds delay on boot when the BIOS has to switch the ports
over from EHCI to xHCI.
This patch should be backported to kernels as old as 3.0, that contain
the commit 69e848c209 "Intel xhci: Support
EHCI/xHCI port switching."

This patch fixes a particularly nasty bug that was revealed by the ring
expansion patches. The bug has been present since the very beginning of
the xHCI driver history, and could have caused general protection faults
from bad memory accesses.
The first thing to note is that a Set TR Dequeue Pointer command can
move the dequeue pointer to a link TRB, if the canceled or stalled
transfer TD ended just before a link TRB. The function to increment the
dequeue pointer, inc_deq, was written before cancellation and stall
support was added. It assumed that the dequeue pointer could never
point to a link TRB. It would unconditionally increment the dequeue
pointer at the start of the function, check if the pointer was now on a
link TRB, and move it to the top of the next segment if so.
This means that if a Set TR Dequeue Point command moved the dequeue
pointer to a link TRB, a subsequent call to inc_deq() would move the
pointer off the segment and into la-la-land. It would then read from
that memory to determine if it was a link TRB. Other functions would
often call inc_deq() until the dequeue pointer matched some other
pointer, which means this function would quite happily read all of
system memory before wrapping around to the right pointer value.
Often, there would be another endpoint segment from a different ring
allocated from the same DMA pool, which would be contiguous to the
segment inc_deq just stepped off of. inc_deq would eventually find the
link TRB in that segment, and blindly move the dequeue pointer back to
the top of the correct ring segment.
The only reason the original code worked at all is because there was
only one ring segment. With the ring expansion patches, the dequeue
pointer would eventually wrap into place, but the dequeue segment would
be out-of-sync. On the second TD after the dequeue pointer was moved to
a link TRB, trb_in_td() would fail (because the dequeue pointer and
dequeue segment were out-of-sync), and this message would appear:
ERROR Transfer event TRB DMA ptr not part of current TD
This fixes bugzilla entry 4333 (option-based modem unhappy on USB 3.0
port: "Transfer event TRB DMA ptr not part of current TD", "rejecting
I/O to offline device"),
https://bugzilla.kernel.org/show_bug.cgi?id=43333
and possibly other general protection fault bugs as well.
This patch should be backported to kernels as old as 2.6.31. A separate
patch will be created for kernels older than 3.4, since inc_deq was
modified in 3.4 and this patch will not apply.

Gary reports that with recent kernels, he notices more xHCI driver

xhci_hcd 0000:03:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk?
We think his Etron xHCI host controller may have the same buggy behavior
as the Fresco Logic xHCI host. When a short transfer is received, the
host will mark the transfer as successfully completed when it should be
marking it with a short completion.
Fix this by turning on the XHCI_TRUST_TX_LENGTH quirk when the Etron
host is discovered. Note that Gary has revision 1, but if Etron fixes
this bug in future revisions, the quirk will have no effect.

- Regmap and devm_* API conversion for TI tps6586x
- Device tree support for Samsung max77686
- devm_* API conversion for STE AB3100
Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
tps65090, da9052 and twl-core.

Pull MFD bits from Samuel Ortiz:
"We have support for a few new drivers:
- Samsung s2mps11
- Wolfson Microelectronics wm5102 and wm5110
- Marvell 88PM800 and 88PM805
- TI twl6041
We also have our regular driver improvements:
- Device tree and IRQ domain support for STE AB8500
- Regmap and devm_* API conversion for TI tps6586x
- Device tree support for Samsung max77686
- devm_* API conversion for STE AB3100
Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
tps65090, da9052 and twl-core."
Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").
In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).
I left that part of commit 2761a63945 just undone.
