Krzysztof Kozlowski 58ae9a2aca ASoC: dt-bindings: Reference common DAI properties
Reference in all sound components which have '#sound-dai-cells' the
dai-common.yaml schema, which allows to use 'sound-name-prefix'
property.

micbias-resistor-k-ohms:
description: The bias resistor to be used in kOhms. The resistor can take
values of 2k, 4k or 8k. If set to 0 it will be off. If this node is not
mentioned or if the value is unknown, then micbias resistor is set to
4k.

description: The bias voltage to be used in mVolts. The voltage can take
values from 1.25V to 3V by 250mV steps. If this node is not mentioned
or the value is unknown, then the value is set to 1.25V.
