Merge tag 'iio-for-3.17a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of new drivers, cleanups and functionality for the 3.17 cycle.

New drivers
* t5403 barometric pressure sensor
* kxcjk1013 accelerometer (with a locking followup fix).
* ak09911 digital compass

Documentation
* ABI docs for proximity added (interface has been there a long time but
  somehow snuck through without being documented)
* Move iio-trig-sysfs documentation out of staging (got left behind when
  the driver moved some time ago).

Cleanups
 * drop the timestamp argument from iio_trigger_poll(_chained) as
   nothing has been done with it for some time.
 * ad799x kerneldoc for ad799x_chip brought up to date.
 * replace a number of reimplementations of the GENMASK macro and
   use the BIT macro to cleanup a few locations.
 * bring the iio_event_monitor example program up to date with new
   device types.
 * fix some incorrect function prototypes in iio_utils.h example code.
 * INDIO_RING_TRIGGERED to INDIO_BUFFER_TRIGGERED fix in docs. This
   got left behind after we renamed it a long time back.
 * fix error handling in the generic_buffer example program.
 * small tidy ups in the iio-trig-periodic-rtc driver.
 * Allow reseting iio-trig-periodic-rtc frequency to 0 (default) after
   it has changed.
 * Trivial tidy ups in coding style in iio_simply_dummy

The {read,write}[bwl] macros used to access the registers in the ni_atmio,
ni_mio_cs, and ni_pcimio drivers and the included ni_mio_common.c file all
rely on a local variable having a specific name. They also require some of
the ni_mio_common code to need a __maybe_unused tag on the devpriv local
variable.

Remove all the macros by converting them into private functions and storing
the callbacks in the private data.

This macro is used to create the private data structure that is used by
the ni_atmio, ni_mio_cs, and ni_pcimio drivers. These drivers all include
the ni_mio_common.c source to provide most of the driver functionality.

The only driver specific information needed to convert the macro into a
proper struct definition is the MAX_N_CALDACS define. This define is used
to size a couple array members in the struct. The ni_atmio and ni_mio_cs
drivers both define MAX_N_CALDACS as 32. The ni_pcimio driver defines it
as (16+16+2). The ni_mio_common file only uses this define to sanity check
that the struct members are large enough for the number of channels in
the calibration subdevice.

Move the MAX_N_CALDACS define to ni_stc.h and set it to the largest number
of caldacs (34).

The ni_atmio and ni_mio_cs drivers also add one additional member to the
private data struct before using the NI_PRIVATE_COMMON macro.

For the ni_atmio driver, the struct pnp_dev pointer can be saved in the
comedi_device as the 'hw_dev'. The (*detach) of this driver can then use
to_pnp_dev() to get it back when detaching the pnp device.

In the ni_mio_cs driver, the struct pcmia_device pointer is not used so
it can simply be removed.

The NI_PRIVATE_COMMON macro can then be converted into a proper struct
definition.

The functions pci9111_trigger_source_set(), pci9111_pretrigger_set(),
and pci9111_autoscan_set() are all used to select the A/D trigger type.
They all do a read/mask/set/write of the A/D Trigger Mode Control register.

Simplify the code by removing these helper functions and combining all
the trigger bits so that a single write can be used to set the register.
