7Required properties
8 - compatible = "qcom,pm8916-wcd-analog-codec";
9 - reg: represents the slave base address provided to the peripheral.
10 - interrupts: List of interrupts in given SPMI peripheral.
11 - interrupt-names: Names specified to above list of interrupts in same
12		    order. List of supported interrupt names are:
13  "cdc_spk_cnp_int" - Speaker click and pop interrupt.
14  "cdc_spk_clip_int" - Speaker clip interrupt.
15  "cdc_spk_ocp_int" - Speaker over current protect interrupt.
16  "mbhc_ins_rem_det1" - jack insert removal detect interrupt 1.
17  "mbhc_but_rel_det" - button release interrupt.
18  "mbhc_but_press_det" - button press event
19  "mbhc_ins_rem_det" - jack insert removal detect interrupt.
20  "mbhc_switch_int"	- multi button headset interrupt.
21  "cdc_ear_ocp_int" - Earphone over current protect interrupt.
22  "cdc_hphr_ocp_int" - Headphone R over current protect interrupt.
23  "cdc_hphl_ocp_det" - Headphone L over current protect interrupt.
24  "cdc_ear_cnp_int" - earphone cnp interrupt.
25  "cdc_hphr_cnp_int" - hphr click and pop interrupt.
26  "cdc_hphl_cnp_int" - hphl click and pop interrupt.
27
28 - clocks: Handle to mclk.
29 - clock-names: should be "mclk"
30 - vdd-cdc-io-supply: phandle to VDD_CDC_IO regulator DT node.
31 - vdd-cdc-tx-rx-cx-supply: phandle to VDD_CDC_TX/RX/CX regulator DT node.
32 - vdd-micbias-supply: phandle of VDD_MICBIAS supply's regulator DT node.
33Optional Properties:
34 - qcom,mbhc-vthreshold-low: Array of 5 threshold voltages in mV for 5 buttons
35			     detection on headset when the mbhc is powered up
36			     by internal current source, this is a low power.
37 - qcom,mbhc-vthreshold-high: Array of 5 thresold voltages in mV for 5 buttons
38			      detection on headset when mbhc is powered up
39			       from micbias.
40- qcom,micbias-lvl:  Voltage (mV) for Mic Bias
41- qcom,hphl-jack-type-normally-open: boolean, present if hphl pin on jack is a
42				     NO (Normally Open). If not specified, then
43				     its assumed that hphl pin on jack is NC
44				     (Normally Closed).
45- qcom,gnd-jack-type-normally-open: boolean, present if gnd pin on jack is
46				    NO (Normally Open). If not specified, then
47				    its assumed that gnd pin on jack is NC
48				    (Normally Closed).
49- qcom,micbias1-ext-cap: boolean, present if micbias1 has external capacitor
50			 connected.
51- qcom,micbias2-ext-cap: boolean, present if micbias2 has external capacitor
52			 connected.
