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

+Description:
+ This file is provided by the iio-trig-sysfs stand-alone trigger
+ driver. Writing this file with any value triggers an event
+ driven driver, associated with this trigger, to capture data
+ into an in kernel buffer. This approach can be valuable during
+ automated testing or in situations, where other trigger methods
+ are not applicable. For example no RTC or spare GPIOs.
+ X is the IIO index of the trigger.
