BTW, I'm not an IIO expert, but from my limited knowledge, it looks like "O"
support in IIO is limited to DACs?

Depends on what you categorize as DACs. There are also
potentiometer/rheostat drivers. They are kind of like DACs but the unit you
control are ohm, rather than current or voltage.

Though they are still in staging there are also things like function generators.

I've been mulling doing a driver for the st-powerstep01 parts as well which
is a smart stepper motor controller.  At that level we'd need to start describing
the connected stepper motors in DT :) Whole chunk of API to define to do that
though - might well take longer than writing the driver.

So in practice yeah - dac like things, but then on the input side they are almost
all really ADCs with some funny analog stuff on the front end ;)

Arguably switches are 1 bit DACs ;)

The distinction here is whether 'what is passing through' the device is knowable.
So regulators and your power switch are well described.  A relay less so unless
we know what load it is switching...

+ it's IIO.  We are open to almost anything as long as we aren't stepping on
any toes!
