1Phosphor 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
7the phosphor-hwmon-readd application, with the limitation that only a single
8iio channel can be configured per iio-hwmon platform instance.  Typically
9device trees are setup with all the iio-channels under a single iio-hwmon
10platform device - doing this will result in undefined behavior from
11phosphor-hwmon-readd.
12
13If a true IIO bridging daemon becomes available in the future, phosphor-hwmon-readd
14will not support hwmon-iio bridge devices in any capacity.
