iio: envelope-detector: ADC driver based on a DAC and a comparator
The DAC is used to find the peak level of an alternating voltage input
signal by a binary search using the output of a comparator wired to
an interrupt pin. Like so:
_

input +------>-------|+ \
| \
.-------. | }---.

| dac|-->--|- / |
| | |_/ |
