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: https://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg787390.html 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 Documentation/hwmon/ina2xx | 8 +- drivers/hwmon/ina2xx.c | 304 +++++++++++++++++++++++++++++++++++++++------ 2 files changed, 269 insertions(+), 43 deletions(-) -- 2.1.3
