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:
17   - reset-gpios : Active low GPIO used to reset the device
19   - cirrus,xtal-ibias:
28   - cirrus,dc-measure:
29    Boolean, define to enable headphone DC impedance measurement.
31   - cirrus,ac-measure:
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.
39   - cirrus,ac-freq:
40    Define the frequencies at which to measure HP AC impedance.
41    Only used if "cirrus,dc-measure" is defined.
