msm8916 analog audio CODEC Bindings for codec Analog IP which is integrated in pmic pm8916, ## Bindings for codec core on pmic: Required properties - compatible = "qcom,pm8916-wcd-analog-codec"; - reg: represents the slave base address provided to the peripheral. - 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,mbhc-vthreshold-low: Array of 5 threshold voltages in mV for 5 buttons detection on headset when the mbhc is powered up by internal current source, this is a low power. - qcom,mbhc-vthreshold-high: Array of 5 thresold voltages in mV for 5 buttons detection on headset when mbhc is powered up from micbias. - qcom,micbias-lvl: Voltage (mV) for Mic Bias - qcom,hphl-jack-type-normally-open: boolean, present if hphl pin on jack is a NO (Normally Open). If not specified, then its assumed that hphl pin on jack is NC (Normally Closed). - qcom,gnd-jack-type-normally-open: boolean, present if gnd pin on jack is NO (Normally Open). If not specified, then its assumed that gnd pin on jack is NC (Normally Closed). - qcom,micbias1-ext-cap: boolean, present if micbias1 has external capacitor connected. - qcom,micbias2-ext-cap: boolean, present if micbias2 has external capacitor connected.
