Hi all,

This patch set adds support for the TI TMAG5273 Low-Power Linear 3D Hall-
Effect Sensor. Additionally to temperature and magnetic X, Y and Z-axes the
angle and magnitude are reported. The sensor is operating in continuous
measurement mode and changes to sleep mode if not used for 5 seconds.

Tests were done on a ROCK3 Model A board using the TMAG5273 evaluation
module.

Changes in v3:
 - Added structs for iio types to iio.h. Using these structs for iio type
   arrays such as IIO_AVAIL_LIST makes the code more readable than just
   using (int *). It was suggested by Andy Shevchenko to move these structs
   to the iio headers to avoid different approaches.
 - dt-bindings: dropped quotes from strings
 - Added include <linux/bitfield.h>
   | Reported-by: kernel test robot <lkp@intel.com> 
 - Added include <linux/bits.h>
 - Removed <asm/unaligned.h>
 - Added missing "static const" for tmag5273_avg_table
 - Documented Device ID
 - Fixed index of tmag5273_scale definition
 - Clarify TMAG5273_MAG_CH_EN_X_Y_Z as an index
 - Removed unnecessary print
 - Introduced tmag5273_write_scale() and tmag5273_write_osr() helper
   functions
 - Use of match_string()
 - Format

Changes in v2:
 Thanks to Krzysztof, Andy and Jonathan for your detailed review and
 explanations on the first version. This patch includes all your
 suggestions and some additional cleanup in the probe function.
