5 - compatible : "cirrus,cs43130", "cirrus,cs4399", "cirrus,cs43131",
8 - reg : the I2C address of the device for I2C
10 - VA-supply, VP-supply, VL-supply, VCP-supply, VD-supply:
11 power supplies for the device, as covered in
12 Documentation/devicetree/bindings/regulator/regulator.txt.
17 - reset-gpios : Active low GPIO used to reset the device
20 When external MCLK is generated by external crystal
21 oscillator, CS43130 can be used to provide bias current
22 for external crystal. Amount of bias current sent is
29 Boolean, define to enable headphone DC impedance measurement.
32 Boolean, define to enable headphone AC impedance measurement.
33 DC impedance must also be enabled for AC impedance measurement.
35 - cirrus,dc-threshold:
36 Define 2 DC impedance thresholds in ohms for HP output control.
37 Default values are 50 and 120 Ohms.
40 Define the frequencies at which to measure HP AC impedance.
41 Only used if "cirrus,dc-measure" is defined.
42 Exactly 10 frequencies must be defined.
43 If this properties is undefined, by default,
44 following frequencies are used:
45 <24 43 93 200 431 928 2000 4309 9283 20000>
46 The above frequencies are logarithmically equally spaced.
