don't care about power, the thing can be powered on all the time. I put a one pulse on a gpio for volume up and a zero pulse on a gpio for volume down, 0 - 63 pulses though.
Question, then, what would be an appropriate widget to use?
You don't need to implement DAPM if you don't want/need to. It'd be helpful to define noop controls for the DAC and output pins like the current TWL4030 driver does but it's not essential.
For your volume control you'll need to write a custom control - all the standard ASoC stuff is for chips with registers.
