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!
