Subject: [PATCH v7 0/5] hwmon: ina2xx: implement chip reinitialization and add new attributes

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.

v7:
- implemented a retry counter for the reinitialization procedure
- using msleep() (since the sleep is > 20ms) instead of mdelay()
  when waiting for the chip update

v6:

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
