Hi Mark, no power, now that would be nice! :) What this was supposed to mean is that the properties are optional, the power of course is not. The DT has really no control over how I wire up my HW and I'd argue most folks just permanently power the TAS5720 since the shutdown current is just a few uAs IIRC in order to save some BOM cost. But I suppose the DT description is such that the Kernel can more intelligently handle things based on what the driver is doing if somebody choses and implements additional regulator/power switch HW. Or did I misunderstand your point? Thanks, Andreas
