Kernel-4.18.0-80.el8_qcom,msm8916-wcd-analog

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.

• 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,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.
