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. v6: - moved the chip initialization and calibration to a separate function and extended the update_device function to check if the chip hasn't been reset and, if so, reinitialize it, - added a new variable to struct ina2xx_data which holds current configuration value in order to be able to restore the config after a reset and reinit, - decided to keep the rshunt value in ina2xx_data in order to be able to restore the shunt value when reinitializing the device, - other minor fixes and improvements, v5: https://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg785734.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 | 266 ++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 243 insertions(+), 31 deletions(-) -- 2.1.3
