|
||
|
|
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
|
||
|

|
||
|
|
detection on headset when mbhc is powered up
|
||
|
|
from micbias.

|
||
|
|
- 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).
|
||
|
|

|
||
|
|
connected.
|
||
|
|
