      staging: iio: tsl2583: fix issue with changes to calibscale and int_time not being set on the chip · 2167769a
      Brian Masney authored 
      When updating the in_illuminance_calibscale and
in_illuminance_integration_time sysfs attributes, these values were not
actually written to the chip. The chip would continue to use the old
parameters. Extracted out tsl2583_set_als_gain() and
tsl2583_set_als_time() functions that are now called when these sysfs
attributes are updated. The chip initialization also calls these these
new functions.

      staging: iio: tsl2583: split out functionality of taos_chip_on() · c908fb76
      Brian Masney authored 
      taos_chip_on() reads an eight member array called taos_config
that contains the desired state of the chip's registers. Only four
of the registers actually need to be written to. The four that do
not need to be written to are for the {low,high} byte of the lower
interrupt threshold and the {low,high} byte of the upper interrupt
threshold. Interrupts are currently not supported by this driver
so there is no need to write to these registers.

This patch removes the taos_config array and separates out the
i2c calls that write to the CONTROL, TIMING, INTERRUPT and ANALOG
registers. This is part of a larger refactor that was split up to
make the code review easier.

      iio: pressure: st_pressure: inline per-sensor data · 91a86a3b
      Linus Walleij authored 
      We have #defines for all the individual sensor registers and
value/mask pairs #defined at the top of the file and used at
exactly one spot.

This is usually good if the #defines give a meaning to the
opaque magic numbers.

However in this case, the semantic meaning is inherent in the
name of the C99-addressable fields, and that means duplication
of information, and only makes the code hard to maintain since
you every time have to add a new #define AND update the site
where it is to be used.

Get rid of the #defines and just open code the values into the
appropriate struct elements. Make sure to explicitly address
the .hz and .value fields in the st_sensor_odr_avl struct
so that the meaning of all values is clear.

This patch is purely syntactic should have no semantic effect.

      iio: imu: inv_mpu6050: inform the i2c mux core about how it is used · 08f3ffce
      Peter Rosin authored 
      The i2c mux core can then take appropriate action depending on if it is
used for an actual i2c mux, or for an arbitrator or gate. In this case
it is used as a gate.

This will make devicetree bindings simpler when they are eventually
added.
