What does this mean?
It's specifying the microphone bias as a function of the AVDD supply voltage. This should be obvious to anyone with any knowledge of the domain, it's a fairly common way of configuring such things.

pin for jack detection. must provide one ofJACKDETECT_ACTIVE_LO or JACKDETECT_ACTIVE_HI followedby debounce time in ms, which must be 5, 10, 20, or 40.
Seems like this could be common. No existing examples to copy?
If it's just a GPIO with a fancy name and some offloading (sounds like it) there's an existing binding for the GPIO.
