Cirrus Logic Arizona class audio SoCs
These devices are audio SoCs with extensive digital capabilities and a range
of analogue I/O.
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.
- wlf,use-jd2 : Use the additional JD input along with JD1 for dual pin jack
detection.
- wlf,use-jd2-nopull : Internal pull on JD2 is disabled when used for
jack detection.
- wlf,jd-invert : Invert the polarity of the jack detection switch
- wlf,micd-software-compare : Use a software comparison to determine mic
presence
- wlf,micd-detect-debounce : Additional software microphone detection
debounce specified in milliseconds.
- wlf,micd-pol-gpio : GPIO specifier for the GPIO controlling the headset
polarity if one exists.
- wlf,micd-bias-start-time : Time allowed for MICBIAS to startup prior to
performing microphone detection, specified as per the ARIZONA_MICD_TIME_XXX
defines.
- wlf,micd-rate : Delay between successive microphone detection measurements,
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.
- wlf,micd-force-micbias : Force MICBIAS continuously on during microphone
detection.
- wlf,gpsw : Settings for the general purpose switch
