just the value of reg 57. Bit(3) decides whether the jack polarity is inverted.
Bit(2) decides whether the button on the headset is inverted.
Bit(1)/(0) decides the mic properity to be OMTP/CTIA or auto.

description: |
value of reg 0x58, Defines the interrupt source.
Bit(2) 1 means button press triggers irq, 0 means not.
Bit(3) 1 means PIN9 is the irq source for jack detection. When set to 0,
bias change on PIN9 do not triggers irq.
Bit(4) 1 means PIN27 is the irq source for jack detection.
Bit(5) 1 means PIN9 is the irq source after MIC detect.
Bit(6) 1 means PIN27 is the irq source after MIC detect.
minimum: 0
maximum: 0x3c

everest,interrupt-clk:
$ref: /schemas/types.yaml#/definitions/uint8
description: |
value of reg 0x59, Defines the interrupt output behavior.
Bit(0-3) 0 means irq pulse equals 512*internal clock
1 means irq pulse equals 1024*internal clock
2 means ...
7 means irq pulse equals 65536*internal clock
8 means irq mutes PA
9 means irq mutes PA and DAC output
Bit(4) 1 means we invert the interrupt output.
Bit(6) 1 means the chip do not detect jack type after button released.
0 means the chip detect jack type again after button released.
