[PATCH v3] iio: adc: ina2xx: Make calibration register value fixed

2017-12-15 Thread Maciej Purski
Calibration register is used for calculating current register in hardware according to datasheet: current = shunt_volt * calib_register / 2048 (ina 226) current = shunt_volt * calib_register / 4096 (ina 219) Fix calib_register value to 2048 for ina226 and 4096 for ina 219 in order to avoid truncat
