+ - interrupt-parent : The parent interrupt controller.
+ - interrupts: List of interrupts in given SPMI peripheral.
+ - interrupt-names: Names specified to above list of interrupts in same
+		    order. List of supported interrupt names are:
+  "cdc_spk_cnp_int" - Speaker click and pop interrupt.
+  "cdc_spk_clip_int" - Speaker clip interrupt.
+  "cdc_spk_ocp_int" - Speaker over current protect interrupt.
+  "mbhc_ins_rem_det1" - jack insert removal detect interrupt 1.
+  "mbhc_but_rel_det" - button release interrupt.
+  "mbhc_but_press_det" - button press event
+  "mbhc_ins_rem_det" - jack insert removal detect interrupt.
+  "mbhc_switch_int"	- multi button headset interrupt.
+  "cdc_ear_ocp_int" - Earphone over current protect interrupt.
+  "cdc_hphr_ocp_int" - Headphone R over current protect interrupt.
+  "cdc_hphl_ocp_det" - Headphone L over current protect interrupt.
+  "cdc_ear_cnp_int" - earphone cnp interrupt.
+  "cdc_hphr_cnp_int" - hphr click and pop interrupt.
+  "cdc_hphl_cnp_int" - hphl click and pop interrupt.
+
+ - clocks: Handle to mclk.
+ - clock-names: should be "mclk"
+ - vdd-cdc-io-supply: phandle to VDD_CDC_IO regulator DT node.
+ - vdd-cdc-tx-rx-cx-supply: phandle to VDD_CDC_TX/RX/CX regulator DT node.
+ - vdd-micbias-supply: phandle of VDD_MICBIAS supply's regulator DT node.
+
+Optional Properties:
+- qcom,micbias1-ext-cap: boolean, present if micbias1 has external capacitor
