This document lists Extcon specific bindings, see the primary binding document:
|
|
../mfd/arizona.txt
|
|
|
|
Optional properties:
|
|
|
|
- wlf,hpdet-channel : Headphone detection channel.
|
|
ARIZONA_ACCDET_MODE_HPL or 1 - Headphone detect mode is set to HPDETL
|
|
ARIZONA_ACCDET_MODE_HPR or 2 - Headphone detect mode is set to HPDETR
|
|
If this node is not mentioned or if the value is unknown, then
|
|
headphone detection mode is set to HPDETL.
|

|
|
specified as per the ARIZONA_MICD_TIME_XXX defines.
|
|
- wlf,micd-dbtime : Microphone detection hardware debounces specified as the
|
|
number of measurements to take, valid values being 2 and 4.
|
|
- wlf,micd-timeout : Timeout for microphone detection, specified in
|
|
milliseconds.
