Subject: [PATCH 0/2] iio: GPIO power switch support
Date: Sun, 11 Dec 2016 23:21:43 +0100 [thread overview]
Message-ID: <1481494905-18037-1-git-send-email-bgolaszewski@baylibre.com> (raw)
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.
