| taiko audio CODEC |
| |
| Required properties: |
| |
| - compatible : "qcom,taiko-slim-pgd" |
| - elemental-addr: codec slimbus slave PGD enumeration address.(48 bits) |
| |
| - qcom,cdc-reset-gpio: gpio used for codec SOC reset. |
| |
| - <supply-name>-supply: phandle to the regulator device tree node |
| - qcom,<supply-name>-voltage - specifies voltage levels for supply. Should be |
| specified in pairs (min, max), units mV. |
| - qcom,<supply-name>-current - specifies max current in mA that can drawn |
| from the <supply-name>. |
| |
| above three properties with "supply-name" set to "qcom,cdc-vdd-buck", "qcom,cdc-vdd-tx-h", |
| "qcom,cdc-vdd-rx-h", "qcom,cdc-vddpx-1", "qcom,cdc-vdd-a-1p2v", "qcom,cdc-vddcx-1", |
| "qcom,cdc-vddcx-2" should be present. |
| |
| - qcom,cdc-micbias-ldoh-v - LDOH output in volts ( should be 1.95 V and 3.00 V). |
| |
| - qcom,cdc-micbias-cfilt1-mv - cfilt1 output voltage in milli volts. |
| - qcom,cdc-micbias-cfilt2-mv - cfilt2 output voltage in milli volts. |
| - qcom,cdc-micbias-cfilt3-mv - cfilt3 output voltage in milli volts. |
| cfilt volatge can be set to max of qcom,cdc-micbias-ldoh-v - 0.15V. |
| |
| - qcom,cdc-micbias1-cfilt-sel = cfilt to use for micbias1 (should be from 1 to 3). |
| - qcom,cdc-micbias2-cfilt-sel = cfilt to use for micbias2 (should be from 1 to 3). |
| - qcom,cdc-micbias3-cfilt-sel = cfilt to use for micbias3 (should be from 1 to 3). |
| - qcom,cdc-micbias4-cfilt-sel = cfilt to use for micbias4 (should be from 1 to 3). |
| - qcom,cdc-micbias1-ext-cap: Boolean. Enable micbias 1 external capacitor mode. |
| - qcom,cdc-micbias2-ext-cap: Boolean. Enable micbias 2 external capacitor mode. |
| - qcom,cdc-micbias3-ext-cap: Boolean. Enable micbias 3 external capacitor mode. |
| - qcom,cdc-micbias4-ext-cap: Boolean. Enable micbias 4 external capacitor mode. |
| |
| - qcom,cdc-slim-ifd-dev - namme of the codec slim interface device. |
| - qcom,cdc-slim-ifd-elemental-addr - codec slimbus slave interface device |
| enumeration address. |
