2019-11-16 | iio: adc: ad7091r5: Add scale and external VREF support | Paul Cercueil | |
The scale can now be obtained with the "in_voltage_scale" file. By default, the scale returned corresponds to the internal VREF of 2.5V. It is possible to use an external VREF (through the REFIN/REFOUT pin of the chip), by passing a regulator to the driver. The scale will then be calculated according to the voltage reported by the regulator.
