For chips with more than 8 bit ADC resolution, received data was always
masked against 0xfff, ie with a 12 bit mask. This can result in bad data
for chips with 10 bit resolution if those chips have higher bits set
(seen with MAX1139).
The receive buffer was defined as char array. This could result in
unintentional sign extensions if the upper bit in a received byte
was set. Since the chip is configured for unipolar mode, we never
have to handle negative values, and sign extensions are never needed.

__iio_update_buffer updates the buffer's bytes_per_datum and length fields.
But the only user of this function just passes in these exact fields, so the
call basically looks like this:
buffer->bytes_per_datum = buffer->bytes_per_datum;
buffer->length = buffer->length;
Which means it is a noop and can be removed. Also remove the function itself,
since it is now unused.

Instantiating the driver with no available regulator results in:

[39711.688835] Oops: 0000 [#1] SMP
Caused by bad probe error path. Fix it.
Driver should also not attempt to free the interrupt in its error path if
none was allocated. Fix that problem as well.
Finally, testing if the regulator was allocated is not necessary in the
remove function, since the probe function bails out if this is the case.
Remove that check.

We have several new drivers, most of the time coming with their sub devices
drivers:
- Austria Microsystem's AS3711
- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader
- Nokia's retu
We also got some notable cleanups and improvements:
- tps6586x got converted to IRQ domains.
- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
APIs and a conversion to the recently added PWM framework.
- sta2x11 gained regmap support.
Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
wm5xxx and wm8xxx patchset.

Far amount of annoying but largely trivial conflicts. Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

Smatch complains that snprintf() returns the number of characters,
not counting the NUL terminator, which *would* have been printed if
there were enough space. In other words the return value could be more
than sizeof(buf).
In this case, we are printing something like "ff.ff\n" which is at most
6 characters and a NUL so that's not an issue. I changed snprintf() to
scnprintf() to silence the warning.
But since the buffer doesn't include space for the NUL terminator, we
need to make it bigger or the "\n" will be truncated off.

It's slightly cleaner to use kstrtouint() because we pass unsigned ints
to adis16136_set_freq(). On 64 bit systems, if the user passed LONG_MIN
then it we would get past the test against zero but crash in
adis16136_set_freq() because we truncate the high bits away.

The ad7796 and ad7797 are similar to the ad7792 and ad7793 but only have a
single differential input instead of two. Also some other features are missing
like the programmable gain amplifier and also not all sampling frequencies
supported by the ad7792/ad7793 are supported by the ad7796/ad7797. This patch
adds new feature flags for the features not present in the ad7796/ad7797. The
patch also adds a struct iio_info field to the chip_info struct, this becomes
necessary since the ad7796/ad7797 needs a special set of sysfs attributes.

The ad7798 and ad7799 are similar to the ad7792 and ad7793 but are missing some
features like the temperature sensor, being able to use an external clocksource
and a few other things. This patch adds a new 'flags' fields to the chip_info
struct which allows to specify which features a certain chip variant supports.
The setup code will then ignore any platform data fields which are related to
non supported features.

Some of the newer generation devices from the ADIS16XXX series have more
registers than what can be supported with the current register addressing
scheme. These devices implement register paging to support a larger register
range. Each page is 128 registers large and the currently active page can be
selected via register 0x00 in each page. This patch implements transparent
paging inside the common adis library. The register read/write interface stays
the same and when a register is accessed the library automatically switches to
the correct page if it is not already selected. The page number is encoded in
the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.
