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. 33 34Optional Properties: 35 - qcom,mbhc-vthreshold-low: Array of 5 threshold voltages in mV for 5 buttons 36 detection on headset when the mbhc is powered up 37 by internal current source, this is a low power. 38 - qcom,mbhc-vthreshold-high: Array of 5 thresold voltages in mV for 5 buttons 39 detection on headset when mbhc is powered up 40 from micbias. 41- qcom,micbias-lvl: Voltage (mV) for Mic Bias 42- qcom,hphl-jack-type-normally-open: boolean, present if hphl pin on jack is a 43 NO (Normally Open). If not specified, then 44 its assumed that hphl pin on jack is NC 45 (Normally Closed). 46- qcom,gnd-jack-type-normally-open: boolean, present if gnd pin on jack is 47 NO (Normally Open). If not specified, then 48 its assumed that gnd pin on jack is NC 49 (Normally Closed). 50- qcom,micbias1-ext-cap: boolean, present if micbias1 has external capacitor 51 connected. 52- qcom,micbias2-ext-cap: boolean, present if micbias2 has external capacitor 53 connected. 54 55Example: 56 57spmi_bus { 58 ... 59 audio-codec@f000{ 60 compatible = "qcom,pm8916-wcd-analog-codec"; 61 reg = <0xf000 0x200>; 62 reg-names = "pmic-codec-core"; 63 clocks = <&gcc GCC_CODEC_DIGCODEC_CLK>; 64 clock-names = "mclk"; 65 qcom,mbhc-vthreshold-low = <75 150 237 450 500>; 66 qcom,mbhc-vthreshold-high = <75 150 237 450 500>; 67 interrupt-parent = <&spmi_bus>; 68 interrupts = <0x1 0xf0 0x0 IRQ_TYPE_NONE>, 69 <0x1 0xf0 0x1 IRQ_TYPE_NONE>, 70 <0x1 0xf0 0x2 IRQ_TYPE_NONE>, 71 <0x1 0xf0 0x3 IRQ_TYPE_NONE>, 72 <0x1 0xf0 0x4 IRQ_TYPE_NONE>, 73 <0x1 0xf0 0x5 IRQ_TYPE_NONE>, 74 <0x1 0xf0 0x6 IRQ_TYPE_NONE>, 75 <0x1 0xf0 0x7 IRQ_TYPE_NONE>, 76 <0x1 0xf1 0x0 IRQ_TYPE_NONE>, 77 <0x1 0xf1 0x1 IRQ_TYPE_NONE>, 78 <0x1 0xf1 0x2 IRQ_TYPE_NONE>, 79 <0x1 0xf1 0x3 IRQ_TYPE_NONE>, 80 <0x1 0xf1 0x4 IRQ_TYPE_NONE>, 81 <0x1 0xf1 0x5 IRQ_TYPE_NONE>; 82 interrupt-names = "cdc_spk_cnp_int", 83 "cdc_spk_clip_int", 84 "cdc_spk_ocp_int", 85 "mbhc_ins_rem_det1", 86 "mbhc_but_rel_det", 87 "mbhc_but_press_det", 88 "mbhc_ins_rem_det", 89 "mbhc_switch_int", 90 "cdc_ear_ocp_int", 91 "cdc_hphr_ocp_int", 92 "cdc_hphl_ocp_det", 93 "cdc_ear_cnp_int", 94 "cdc_hphr_cnp_int", 95 "cdc_hphl_cnp_int"; 96 vdd-cdc-io-supply = <&pm8916_l5>; 97 vdd-cdc-tx-rx-cx-supply = <&pm8916_l5>; 98 vdd-micbias-supply = <&pm8916_l13>; 99 #sound-dai-cells = <1>; 100 }; 101};
