Cleaning up the description: msm8916 audio CODEC Codec IP is divided into two parts: * analog, which is integrated into pmic pm8916 * digital, which is integrated into LPASS on the SOC Codec registers are also split across pmic and LPASS. Analog codec is controlled via spmi bus to pmic. > +## Bindings for codec core on pmic: > + > +Required properties > + - compatible = "qcom,msm8916-pmic-wcd-codec"; OK. Looking at this again, I think its better just to drop the pmic. > + "spk_cnp_int" - Speaker click and pop interrupt > + "spk_clip_int" - Speaker clip interrupt > + "spk_ocp_int" - Speaker over current protect interrupt. > + "ins_rem_det1" - jack insert removal detect interrupt 1. > + "but_rel_det" - button release interrupt > + "but_press_det" - button press event > + "ins_rem_det" - jack insert removal detect interrup > + "mbhc_int" - multi button headset interrupt. > + "ear_ocp_int" - Earphone over current protect interrupt. > + "hphr_ocp_int" - Headphone R over current protect interrupt. > + "hphl_ocp_det" - Headphone L over current protect interrupt > + "ear_cnp_int" - earphone cnp interrupt. > + "hphr_cnp_int" - hphr click and pop interrupt. > + "hphl_cnp_int" - hphl click and pop interrupt Please use labels that more closely match the HW spec: "cdc_spk_cnp_int" "cdc_spk_clip_int" "cdc_spk_ocp_int" "mbhc_ins_rem_det1" "mbhc_but_rel_det" "mbhc_but_press_det" "mbhc_ins_rem_det" "mbhc_switch_int" "cdc_ear_ocp_int" "cdc_hphr_ocp_int" "cdc_hphl_ocp_int" "cdc_ear_cnp_int" "cdc_hphr_cnp_int" "cdc_hphl_cnp_int" -- Kenneth Westfield Qualcomm Innovation Center, Inc.
