These devices are actually not trivial and can receive basic configuration (e.g. power up mode, CNTL pin polarity, expected input voltage), however devicetree support for configuration was never added. Therefore in current state the devices are used only in read-only mode and have trivial bindings, so document them to have basic dtschema tests.
