Please provide defines for these as part of the binding. It's not clear to me why leaving the micbias powered down is a sane default, it'll only be powered up if it's connected to something and used which doesn't seem altogether sane. I'd suggest picking 2.0V (the lowest voltage so least likely to cause damage).
