The default chip-delay of 25us is a bit too tight for some DNS-320's,
and D-Link seem to specify 30us in their kernels for both devices.
Increase to 35us to make sure the NAND is stable.

Now that the EHCI driver has DT support, drop old style configuration
of it and add DT in its place. Since all the boards enable the EHCI,
enable it by default in kirkwood.dtsi. Any new boards which don't have
USB can specifically disable it.

NAND chip detection, introduced by some rework which went into 3.7. The
initial fix wasn't quite complete, so it's in two parts. In fact the
first part is committed twice (Artem committed his own copy of the same
patch) and I've merged Artem's tree into mine which already had that fix.
I'd have recommitted that to make it somewhat cleaner, but figured by
this point in the release cycle it was better to merge *exactly* the
commits which have been in linux-next.
If I'd recommitted, I'd also omit the sparse warning fix. But it's there,
and it's harmless — just marking one function as 'static' in onenand code.
This also includes a couple more fixes for stable: an AB-BA deadlock in
JFFS2, and an invalid range check in slram.

"Distilled down version of bug fixes for 3.7. The patches have been
well tested. If you notice that commit dates are from today, it's
because I pulled less important bits out and shuffled them into the
3.8 mix. Apart from that, no changes, base still the same.
It contains:
- Fix for aoe, don't run request_fn while it's plugged.
- Fix for a regression in floppy since 3.6, which causes problems if
no floppy is found.
- Stable fix for blk_exec(), don't touch a request after it has been
sent to the scheduler (and the device as well).
- Five fixes for various nasties in mtip32xx."
* 'for-linus' of git://git.kernel.dk/linux-block:
block: Don't access request after it might be freed
mtip32xx: Fix padding issue
aoe: avoid running request handler on plugged queue
mtip32xx: fix potential NULL pointer dereference in mtip_timeout_function()
mtip32xx: fix shift larger than type warning
mtip32xx: Fix incorrect mask used for erase mode
mtip32xx: Fix to make lba address correct in big-endian systems
mtip32xx: fix potential crash on SEC_ERASE_UNIT
dm: fix deadlock with request based dm and queue request_fn recursion
floppy: destroy floppy workqueue before cleaning up the queue
This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.
The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.
This fix takes the same approach as 0bce04b that solved the equivalent problem
for of_address_to_resource.

Make pnpacpi_add_device() ignore ACPI device nodes already associated
with struct device objects representing physical devices.
In particular, this will prevent PNP device objects from being
created for ACPI device nodes already associated with platform
devices.
This change was originally proposed by Mika Westerberg.

dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.

On BE2 chip, an interrupt being raised even when EQ is in un-armed state has
been observed a few times. This is not expected and has never been
observed on BE3/Lancer chips.
As a consequence, be_msix()::events_get() and be_poll()::events_get()
can race and notify an EQ wrongly causing a CEV UE. The other possible
side-effect would be traffic stalling because after notifying EQ,
napi_schedule() is ignored as NAPI is already running.
This patch fixes this issue by counting events only in be_poll().

Instead of storing the number of wake-up frame filter registers
in the pdata structure, this patch changes the driver to detect
the type of device we have and store its available features.
The new two features will be used in future patches.

Paul Gortmaker says:
====================
The most interesting thing here, at least from a user perspective,
is the broadcast link fix -- where there was a corner case where
two endpoints could get in a state where they disagree on where
to start Rx and ack of broadcast packets.
There is also the poll/wait changes which could also impact
end users for certain use cases - the fixes there also better
align tipc with the rest of the networking code.
The rest largely falls into routine cleanup category, by getting
rid of some unused routines, some Kconfig clutter, etc.
