[PATCH v8 0/5] hwmon: ina2xx: implement chip reinitialization and add new attributes
From: Bartosz Golaszewski
Date: Mon Jan 05 2015 - 09:21:13 EST
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
