[PATCH v3 6/8] iio: dpot-dac: DAC driver based on a digital potentiometer

2016-10-23 Thread Peter Rosin
It is assumed that the dpot is used as a voltage divider between the current dpot wiper setting and the maximum resistance of the dpot. The divided voltage is provided by a vref regulator. .--. .---. | | | vref |--'.---. | regulator |--.|
