Included is the patch previously set as the fourth round for 3.13 which was
to late to be appropriate.
* Another endian fix (ad799x adc) due to missuse of the IIO_ST macro (which
is going away very shortly)
* A reversed error check in ad5933 which will make the probe fail.
* A buffer overflow in the example code in the documentation.
* ad799x was freeing an irq that might or might not have been requested.
* tsl2563 was checking the wrong element of chan_spec for modifiers. Thus some
sysfs reads would give the wrong values.
* A missing dependency on HAS_IOMEM in spear_adc and lpc32xx was causing some
test build failures (on s390 and perhaps elsewhere).
I also have a few fixes queued up for things that went in during the 3.14
merge window which will follow as a separate pull request (to avoid rebasing
my tree).

Pull networking updates from David Miller:
1) BPF debugger and asm tool by Daniel Borkmann.
2) Speed up create/bind in AF_PACKET, also from Daniel Borkmann.
3) Correct reciprocal_divide and update users, from Hannes Frederic
Sowa and Daniel Borkmann.
4) Currently we only have a "set" operation for the hw timestamp socket
ioctl, add a "get" operation to match. From Ben Hutchings.
5) Add better trace events for debugging driver datapath problems, also
from Ben Hutchings.
6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we
have a small send and a previous packet is already in the qdisc or
device queue, defer until TX completion or we get more data.
7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko.
8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel
Borkmann.
9) Share IP header compression code between Bluetooth and IEEE802154
layers, from Jukka Rissanen.
10) Fix ipv6 router reachability probing, from Jiri Benc.
11) Allow packets to be captured on macvtap devices, from Vlad Yasevich.
12) Support tunneling in GRO layer, from Jerry Chu.
13) Allow bonding to be configured fully using netlink, from Scott
Feldman.
14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can
already get the TCI. From Atzm Watanabe.
15) New "Heavy Hitter" qdisc, from Terry Lam.
16) Significantly improve the IPSEC support in pktgen, from Fan Du.
17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom
Herbert.
18) Add Proportional Integral Enhanced packet scheduler, from Vijay
Subramanian.
19) Allow openvswitch to mmap'd netlink, from Thomas Graf.
20) Key TCP metrics blobs also by source address, not just destination
address. From Christoph Paasch.
21) Support 10G in generic phylib. From Andy Fleming.
22) Try to short-circuit GRO flow compares using device provided RX
hash, if provided. From Tom Herbert.
The wireless and netfilter folks have been busy little bees too.

This was originally reported by Craig Markwardt on Zubair Lutfullah's
blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email
address known.
The code first counted the number of enabled channels, then created an
array to hold information about them. The code that filled this array then
stored whether a given element was enabled inside the array. Curriously
this element was never used. Craig's patch added a local temporary variable
to avoid the buffer overrun. Jonathan then removed the original enabled
element of the structure as it was not needed at all.

Some LRADC channels have fixed pre-dividers and all have an optional
divider by two which allows a maximum input voltage of VDDIO - 50mV.
This patch
- adds the scaling info flag to all channels
- grabs the max reference voltage per channel
(where the fixed pre-dividers apply)
- allows to read the scaling attribute (computed from the Vref)

New drivers
* HID inclinometer driver.
* DHT11 humidity driver. Note that previous humidity drivers have been in
hwmon, but no one was ever entirely happy with that, and they should find
a more comfortable home in IIO (their original placement in hwmon was my
fault - oops). As this is our first humidity driver, core support is also
added.
New features
* Two of mxs-lradc channels are internally wired to a temperature sensor,
make this explicit in the driver by providing the relevant temperature
channel.
* Add support for blocking IO on buffers.
* Add a data_available call back to the interface between buffer implementations
and the core. This is much cleaner than the old, 'stufftoread' flag.
Implemented in the kfifo buffer.
Cleanups
* Last user of the old event configuration interface is converted and the
old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard
work!
* Replace all remaining instances of the IIO_ST macro with explicit filling
of the scan_type structure within struct iio_chan_spec. This macro was a
bad idea, that rapidly ceased to cover all elements of the structure.
Miss reading of the macro arguements has led to a number of bugs so lets
just get rid of it. The final removal patch is awaiting for some fixes
to make their way into mainline.
In a couple of drivers, no elements of scan_type were even being used so
in those case, it has been dropped entirely.
* Drop a couple of of_match_ptr helper uses in drivers where devicetree is
not optional and hence the structures being protected by this always exist.
* Fix up some cases where data was read from a device in a particular
byte order, but he code placed it into a s16 or similar. These were
highlighted by Sparse.
* Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers
core code.
* ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code
and possibly avoiding issues with i2c bus drivers that assume they can dma
directly into the buffer. Note that this cannot currently happen as the the
i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually
passed to the bus driver. I missed this element of the commit message
and don't think it is major enough to rebase the iio tree.
* ad5791 and ad5504 stop storing buffers on the stack for an SPI driver.
Unlike the i2c drivers, this is a real issue for SPI drivers which can dma
directly into the buffer supplied.

Due to use of the IIO_ST macro, the endianness element of scan_type was
not being set. The result is that it will default to the cpu endianness
whereas this driver will fill the buffer with big endian data. Thus for
little endian machines, userspace will miss interpret the data.

IIO_ST is going away as it is a pain to maintain. Note that this driver
currently ensures all fields are converted to the native endianness
to keep things consistent across the different bus types.

This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness. This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
converting the channel and generating thoroughly trashed data.

The mxs LRADC is able to read an internal die temperature sensor. The
temperature has to be calculated from the value read on channel 8 and channel 9.
To be able to expose the result to hwmon, implement iio channel 8 as
(channel 9 - channel 8). Then, implement IIO_CHAN_INFO_SCALE and
IIO_CHAN_INFO_OFFSET so that it can be processed by hwmon through the in kernel
provider/consumer mechanism.

This mostly consists of patches that didn't quite make the last cycle. Lots
of interesting things under review currently.
Core:
- Add devm_iio_device_register/unregister. I took some convincing on whether
there would be many devices that really were simple enough to need no
explicit actions on removal. Turns out there are some.
- Move some stray docs to above the relevant implemenation.
- Drop a redundant repeated check on the fact the trigger has actually changed
when there is a userspace attempt change it.
Drivers:
New drivers
- Freescale MPL3115A2 Pressure / temperature sensor
New functionality
- hid_sensors: add sensitivity support.
DT bindings
- tsl2563
- hmc5843
Cleanups
- Drop unused scan_type from viperboard adc driver.
- devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
and ad2s1200. Note that this was proposed in a number of other drivers
and this revealed a number of missorderings in remove functions. Also for
now I have blocked this on any device that any hardware suspend suport on
the basis that we probably want to power down devices if they have no driver
support loaded.

The usual mixed bag of fixes.
* 3 cases where kconfig dependencies were missing. We need to keep a closer
eye on this in new drivers.
* hid_sensors was abusing the iio_dev->trigger pointer. We had a round
of clearing this out some time ago but this driver clearly slipped through.
* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
concertive effort to finish removing.
* Avoid a double free introduced by recent buffer reference counting in the
one driver that (quite reasonably!) does things differently (am335x)
* A missing mutex_unlock in kxsd9 that means that driver has been non
functional for some time and no one noticed (including me who for once
actually has one of the supported devices).
* An incorrect assumption about the parameters of sign_extend32 in mcp3422.
So nothing controversial. The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.

As well as the usual driver updates and cleanups there's a few
improvements to the core here:
- The start of some improvements to factor out more of the SPI message
loop into the core. Right now this is just simplifying the code a
bit but hopefully next time around we'll also have managed to roll
out some noticable performance improvements which drivers can take
advantage of.
- Support for loading modules for ACPI enumerated SPI devices.
- Managed registration for SPI controllers.
- Helper for another common I/O pattern.

New Drivers
* cm36651 combined RGB light and proximity sensor.
Core improvements
* Some more fixes and cleanups related to buffers. These include the second
half of a series which went is as fixes. The basis for delaying until the
next merge window is that some are too invasive for this late in a cycle
and others only effect code paths current unused in the mainline tree.
In this case we have:
* protecting against concurrent userspace access
* fixing a memory leak if a device goes away
* avoiding always reallocating the buffer whether or not it has changed
(a bug fix, but one with no functional changes other than a small speed
improvement.)
* Add reference counting for buffers to ensure they hang around if open
from userspace or in kernel when the device is forcefully removed.
* Return -ENODEV for buffer access operations when the device has gone
away.
* Add proper locking for iio_update_buffers (currently we only have one
buffer per device in mainline, but an input bridge driver is under
development which would make this bug 'real'.)
* Wake up anyone waiting on a buffer if the device is unregistered. A
subsequent read will fail, notifying userspace that the device is no
longer there rather than having it wait possibly for ever.
* Move the iio_sw_preenable functionality into the core. This avoids drivers
having to 'know' about how the buffers are implemented and is called by
almost all drivers anyway. Those that don't call it are not harmed by it
being called.
* New registration approach for information (i.e. sysfs attributes) about
events. Much more generic and now similar to how the equivalent is
handled for channel information. The events infrastructure had been left
behind by other changes so this brings it back in line.
* Using the new events registration approach, add a hysterisis event_info
element and apply this to those drivers with this property.
* A little unitialized variable bug in the generic_buffer.c example.
* Factor out the code for freeing lists of IIO Device attributes to avoid
some repitition.
Driver cleanups
* At91 driver gains touch screen support and some related fixes.
* Follow up series of patches removing the now redundant
iio_sw_buffer_preenable calls.
* Lots of conversions to the new event registration methods.
* Another round of hmc5843 cleanups as that driver moves towards graduating
from staging.
* Make some SoC drivers buildable if COMPILE_TEST is used. Follow up fixes
for a few bits and bobs that revealed.
* Add explicit includes of linux/of.h to those drivers making us of linux/of.h

subsequent read will fail, notifying userspace that the device is no
longer there rather than having it wait possibly for ever.
* Move the iio_sw_preenable functionality into the core. This avoids drivers
having to 'know' about how the buffers are implemented and is called by
almost all drivers anyway. Those that don't call it are not harmed by it
being called.
* New registration approach for information (i.e. sysfs attributes) about
events. Much more generic and now similar to how the equivalent is
handled for channel information. The events infrastructure had been left
behind by other changes so this brings it back in line.
* Using the new events registration approach, add a hysterisis event_info
element and apply this to those drivers with this property.
* A little unitialized variable bug in the generic_buffer.c example.
* Factor out the code for freeing lists of IIO Device attributes to avoid
some repitition.
Driver cleanups
* At91 driver gains touch screen support and some related fixes.
* Follow up series of patches removing the now redundant
iio_sw_buffer_preenable calls.
* Lots of conversions to the new event registration methods.
* Another round of hmc5843 cleanups as that driver moves towards graduating
from staging.
* Make some SoC drivers buildable if COMPILE_TEST is used. Follow up fixes
for a few bits and bobs that revealed.
* Add explicit includes of linux/of.h to those drivers making us of linux/of.h
