33 just the value of reg 57. Bit(3) decides whether the jack polarity is inverted.

35 Bit(1)/(0) decides the mic property to be OMTP/CTIA or auto.

66 value of reg 0x58, Defines the interrupt source.
67 Bit(2) 1 means button press triggers irq, 0 means not.
68 Bit(3) 1 means PIN9 is the irq source for jack detection. When set to 0,
69 bias change on PIN9 do not triggers irq.
70 Bit(4) 1 means PIN27 is the irq source for jack detection.
71 Bit(5) 1 means PIN9 is the irq source after MIC detect.
72 Bit(6) 1 means PIN27 is the irq source after MIC detect.

80 value of reg 0x59, Defines the interrupt output behavior.
81 Bit(0-3) 0 means irq pulse equals 512*internal clock
82 1 means irq pulse equals 1024*internal clock
83 2 means ...
84 7 means irq pulse equals 65536*internal clock
85 8 means irq mutes PA
86 9 means irq mutes PA and DAC output
87 Bit(4) 1 means we invert the interrupt output.
88 Bit(6) 1 means the chip do not detect jack type after button released.
89 0 means the chip detect jack type again after button released.
