[PATCH v6 0/3] add ti tmag5273 driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 v6:
 - Defined TMAG5273_MAX_REG
 - Added comment for wrong device ID
 
Changes in v5:
 - Fixed dev_err_probe
 - Removed unnecessary '&' for function pointers
 - Removed warning for device tree reading failure as Linux should not
   validate device tree.
 - Added comment for device name
 - Added tmag5273_wake_up() and improved comments
 - Reformatted pm_ops
 
Changes in v4:
 - Add only struct for IIO_VAL_INT_PLUS_MICRO iio type to iio.h.
 - Simplified tmag5273_write_scale()
 - Removed unnecessary  != 0
 - Fixed regmap max_register
 - Simplified tmag5273_read_device_property()
 - Fixed some line breaks.

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@xxxxxxxxx> 
 - 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.
