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.

OK. Looking at this again, I think its better just to drop the pmic.
Yep..

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"
Yes, we can do that to match the specs.
