This series is aimed at improving the support for baylibre-acme[1] power measurement capes.
We would like to add support for power-cycling of devices measured using TI INA226 ADCs. An example use case would be measuring the power consumption of a development board during boot and power-cycling it remotely using a GPIO power switch. The first patch proposes to add a new DT binding for describing simple power switches. The second adds a simple IIO driver exposing a single attribute. The motivation for using the IIO framework is the fact that we already use it for reading the data from the ADC and that power-cycling the measured devices is an integral part of our use case. Users would find it convenient to be able to use libiio as the single interface.
