How is this different than a GPIO regulator? The input and output voltages just happen to be the same. I could be convinced this is different enough to have a different compatible, but it somewhat seems you want to use this for IIO, so you are creating a different binding for that usecase. Rob

Some boards are equipped with simple, GPIO-driven power load switches. An example of such ICs is the TI tps229* series. Add device tree bindings allowing to describe them.
