The IIO_ST macro no longer covers all the elements of struct scan_type
and has this has lead to some bugs being introduced.
The drivers are easier to follow with this structure being directly
filled so that is now preferred.

Note this also sets the endianness to big endian whereas it would
previously have defaulted to the cpu endian. Hence technically

A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel. Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

Currently the IIO buffer interface only allows non-blocking reads. This patch
adds support for blocking IO. In blocking mode the thread will go to sleep if no
data is available and will wait for the buffer implementation to signal that new
data is available by waking up the buffers waitqueue.

This patch implements the data_available() callback for the kfifo buffer instead
of using the stufftoread flag. The kfifo used by the buffer already knows
whether it is empty or not based on the position of its read and write pointer.
Using this makes it a lot easier to tell whether data is available or not and it
is not necessary to take special measures to ensure that no race conditions
between reading and writing from the buffer occur.
Note, that we still have to take the buffers lock to protect against concurrent
resizeing of the kfifo.

This patch adds a new data_available() callback to the iio_buffer_access_funcs
struct. The callback is used to indicate whether data is available in the buffer
for reading. It is meant to replace the stufftoread flag from the iio_buffer
struct. The reasoning for this is that the buffer implementation usually can
determine whether data is available rather easily based on its state, on the
other hand it can be rather tricky to update the stufftoread flag in a race free
way.

In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

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.
