[PATCH v8 0/5] hwmon: ina2xx: implement chip reinitialization and add new attributes

[Bartosz Golaszewski <bgolaszewski@baylibre.com>]

This series implements a mechanism to detect if the chip is in its POR state
and reinitialize it if needed. It also extends the sysfs interface to make the
driver configurable at run-time.

The shunt_resistor attribute allows to change the shunt resistance value
at run-time in cases where ina2xx used to do the measurement isn't integrated
with the shunt.

The avg_rate attribute allows to increase/decrease noise reduction.

v8:
- accept averaging rate values more flexibly and round them to the nearest
  correct value
- don't call ina2xx_update_device() in ina226_set_avg()
- make sure the registers are going to be re-read after setting the averaging
  rate

v7:

Bartosz Golaszewski (5):
  hwmon: ina2xx: reinitialize the chip in case it's been reset
  hwmon: ina2xx: remove a stray new line
  hwmon: ina2xx: don't accept shunt values greater than the calibration factor
  hwmon: ina2xx: make shunt resistance configurable at run-time
  hwmon: ina2xx: allow to change the averaging rate at run-time
