H A DREADME.iio.md4 same way that hwmon devices are bridged by the phosphor-hwmon-readd application.
6 Until a daemon can be written, the hwmon-iio bridge driver can be used with the
7 phosphor-hwmon-readd application, with the limitation that only a single iio
8 channel can be configured per iio-hwmon platform instance. Typically device
9 trees are setup with all the iio-channels under a single iio-hwmon platform
10 device - doing this will result in undefined behavior from phosphor-hwmon-readd.
13 phosphor-hwmon-readd will not support hwmon-iio bridge devices in any capacity.
