iio: imu: st_lsm6dsx: add addr/max_word_len to st_lsm6dsx_read_block()

2018-09-02T20:29:24+00:00

Add reg addr and max_word_len parameters to st_lsm6dsx_read_block
since LSM6DSO will use a different register address to read samples
from the FIFO and a different sample len

iio: imu: st_lsm6dsx: make st_lsm6dsx_check_odr() non-static

2018-09-02T20:28:48+00:00

Remove static qualifier from st_lsm6dsx_check_odr() definition in order to
use it for the support of new devices

iio: imu: st_lsm6dsx: add read_fifo callback to fifo_ops

2018-09-02T20:26:38+00:00

Remove static qualifier from st_lsm6dsx_read_fifo definition and
introduce read_fifo function pointer in fifo_ops data structure
in order to run the proper read_fifo routine since other compliant
devices will use a different FIFO queueing scheme.

iio: imu: st_lsm6dsx: take into account ts samples in wm configuration

2018-09-02T20:19:53+00:00

Take into account hw timer samples in pattern length computation done
in st_lsm6dsx_update_watermark routine for watermark configuration.
Moreover use samples in pattern (sip) already computed in
st_lsm6dsx_update_decimators routine

Second set of IIO new device support, features and cleanups.

There are also a couple of fixes that can wait for the coming merge
window.

Core new features

* Support for phase channels (used in time of flight sensors amongst
  other things)
* Support for deep UV light channel modifier.

New Device Support

* AD4758 DAC
  - New driver and dt bindings.
* adxl345
  - Support the adxl375 +-200g part which is register compatible.
* isl29501 Time of flight sensor.
  - New driver
* meson-saradc
  - Support the Meson8m2 Socs - right now this is just an ID, but there will
    be additional difference in future.
* mpu6050
  - New ID for 6515 variant.
* si1133 UV sensor.
  - New driver
* Spreadtrum SC27xx PMIC ADC
  - New driver and dt bindings.

Features

* adxl345
  - Add calibration offset readback and writing.
  - Add sampling frequency control.

Fixes and Cleanups

* ad5933
  - Use a macro for the channel definition to reduce duplication.
* ad9523
  - Replace use of core mlock with a local lock. Part of ongoing efforts
    to avoid confusing the purpose of mlock which is only about iio core
    state changes.
  - Fix displayed phase which was out by a factor of 10.
* adxl345
  - Add a link to the datasheet.
  - Rework the use of the address field in the chan_spec structures to
    allow addition of more per channel information.
* adis imu
  - Mark switch fall throughs.
* at91-sama5d2
  - Fix some casting on big endian systems.
* bmp280
  - Drop some DT elements that aren't used and should mostly be done from
    userspace rather than in DT.
* hx711
  - add clock-frequency dt binding and resulting delay to deal with capacitance
    issue on some boards.
  - fix a spurious unit-address in the example.
* ina2xx
  - Avoid a possible kthread_stop with a stale task_struct.
* ltc2632
  - Remove some unused local variables (assigned but value never used).
* max1363
  - Use device_get_match_data to remove some boilerplate.
* mma8452
  - Mark switch fall throughs.
* sca3000
  - Fix a missing return in a switch statement (a bad fallthrough
    previously!)
* sigma-delta-modulator
  - Drop incorrect unit address from the DT example.
* st_accel
  - Use device_get_match_data to drop some boiler plate.
  - Move to probe_new for i2c driver as second parameter not used.
* st_sensors library
  - Use a strlcpy (safe in this case).
* st_lsm6dsx
  - Add some error logging.
* ti-ads7950
  - SPDX
  - Allow simultaneous buffered and polled reads. Needed on a Lego Mindstorms
    EV3 where some channels are used for power supply monitoring at a very low
    rate.
* ti-dac5571
  - Remove an unused variable.
* xadc
  - Drop some dead code.

driver functions correctly on a LG Nexus 5 (hammerhead) phone.
