|
|
|
|
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.
