Commit d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some
changes from the vendor driver that made it newly important that the
calculated hardware version correctly include the CHIP_92D bit, as all
of the IS_92D_* macros were changed to depend on it. However, this bit
was being unset for dual-mac, dual-phy devices. The vendor driver
behavior was modified to not do this, but unfortunately this change was
not picked up along with the others. This caused scanning in the 2.4GHz
band to be broken, and possibly other bugs as well.
This patch brings the version calculation logic in parity with the
vendor driver in this regard, and in doing so fixes the regression.
However, the version calculation code in general continues to be largely
incoherent and messy, and needs to be cleaned up.

of_get_named_gpio_flags() and of_get_named_gpio() return -EPROBE_DEFER if the
respective GPIO is not (yet) available. This is useful if driver's probe()
functions try to get a GPIO whose controller isn't probed yet. Thus, the driver
can be probed again later on.
The function still returns -EINVAL on other errors (parse error or node doesn't
exist). This way, the case of an optional/intentionally missing GPIO is handled
appropriately.

Since users must be explicitly provided with a GPIO number in order to
request one the overwhelmingly common case for failing to request will
be that the required GPIO driver has not yet registered and we should
therefore defer until it has registered.
In order to avoid having to code this logic in individual drivers have
gpio_request() return -EPROBE_DEFER when failing to look up the GPIO.
Drivers which don't want this behaviour can override it if they desire.

TCA6424 is a low voltage 24 bit I2C and SMBus I/O expander of pca953x family
similar to its 16 bit predecessor TCA6416. It comes with three 8-bit active
Input, Output, Polarity Inversion and Configuration registers each. The polarity
of Input ports can be reversed by setting the appropiate bit in Polarity
Inversion registers.
The variables corresponding to Input, Output and Configuration registers have
already been updated to support 24 bit values. This patch thus updates the
invert variable of PCA953X platform data to support 24 bit.

Since the bank->dbck initialization in a one time operation there
is no need to keep this within gpio_debounce(). Therefore, moving
clk_get(bank->dbck) to omap_gpio_mod_init(). Since the value of
bank->dbck would be NULL at the beginning, this check has been
removed.

This patch adds on-demand wakeup request sending (and re-sendind) when
we are in low-power state. When the controller enters this state it will
send a sleep message after which the host is not allowed to send any
other packets until a wakeup request has been sent and the woken message
received as a response to it. The wakeup requests are re-sent
periodically until a woken message is received.

These patches implement the final mechanism necessary to really allow
us to go without the route cache in ipv4.
We need a place to have long-term storage of PMTU/redirect information
which is independent of the routes themselves, yet does not get us
back into a situation where we have to write to metrics or anything
like that.
For this we use an "next-hop exception" table in the FIB nexthops.
The one thing I desperately want to avoid is having to create clone
routes in the FIB trie for this purpose, because that is very
expensive. However, I'm willing to entertain such an idea later
if this current scheme proves to have downsides that the FIB trie
variant would not have.
In order to accomodate this any such scheme, we need to be able to
produce a full flow key at PMTU/redirect time. That required an
adjustment of the interface call-sites used to propagate these events.
For a PMTU/redirect with a fully specified socket, we pass that socket
and use it to produce the flow key.
Otherwise we use a passed in SKB to formulate the key. There are two
cases that need to be distinguished, ICMP message processing (in which
case the IP header is at skb->data) and output packet processing
(mostly tunnels, and in all such cases the IP header is at ip_hdr(skb)).
We also have to make the code able to handle the case where the dst
itself passed into the dst_ops->{update_pmtu,redirect} method is
invalidated. This matters for calls from sockets that have cached
that route. We provide a inet{,6} helper function for this purpose,
and edit SCTP specially since it caches routes at the transport rather
than socket level.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
IIO fixes for elements queued for 3.6 merge window.
3 types of fix here.
1) Incorrect pointer casting via phys_addr_t which causes
trouble on some architectures.
2) request_irq and free_irq dev_id parameters not matching.
3) Inconsistencies in client_data for some i2c devices
(writing one pointer and expecting another later).

class_create if succeeded returns a pointer to the struct class,
and if it fails, it returns a value enclosed by the pointer, which
can be read by using PTR_ERR.
Handle the error and return it.
result is for error checking of the alloc_chrdev_region, instead
ret can be used, and also if the alloc_chrdev_region fail,
we are still returning -ENODEV, use ret and the error path will
take care of returning of the ret.
