1# Phosphor OpenBMC and IIO devices
2
3Phosphor OpenBMC currently does not provide an IIO device to DBUS bridge in the
4same way that hwmon devices are bridged by the phosphor-hwmon-readd application.
5
6Until a daemon can be written, the hwmon-iio bridge driver can be used with the
7phosphor-hwmon-readd application, with the limitation that only a single iio
8channel can be configured per iio-hwmon platform instance. Typically device
9trees are setup with all the iio-channels under a single iio-hwmon platform
10device - doing this will result in undefined behavior from phosphor-hwmon-readd.
11
12If a true IIO bridging daemon becomes available in the future,
13phosphor-hwmon-readd will not support hwmon-iio bridge devices in any capacity.
