1 Cirrus Logic Arizona class audio SoCs
3 These devices are audio SoCs with extensive digital capabilities and a range
6 This document lists Extcon specific bindings, see the primary binding document:
11 - wlf,hpdet-channel : Headphone detection channel.
12 ARIZONA_ACCDET_MODE_HPL or 1 - Headphone detect mode is set to HPDETL
13 ARIZONA_ACCDET_MODE_HPR or 2 - Headphone detect mode is set to HPDETR
14 If this node is not mentioned or if the value is unknown, then
15 headphone detection mode is set to HPDETL.
17 - wlf,use-jd2 : Use the additional JD input along with JD1 for dual pin jack
19 - wlf,use-jd2-nopull : Internal pull on JD2 is disabled when used for
21 - wlf,jd-invert : Invert the polarity of the jack detection switch
23 - wlf,micd-software-compare : Use a software comparison to determine mic
25 - wlf,micd-detect-debounce : Additional software microphone detection
26 debounce specified in milliseconds.
27 - wlf,micd-pol-gpio : GPIO specifier for the GPIO controlling the headset
28 polarity if one exists.
29 - wlf,micd-bias-start-time : Time allowed for MICBIAS to startup prior to
30 performing microphone detection, specified as per the ARIZONA_MICD_TIME_XXX
32 - wlf,micd-rate : Delay between successive microphone detection measurements,
33 specified as per the ARIZONA_MICD_TIME_XXX defines.
34 - wlf,micd-dbtime : Microphone detection hardware debounces specified as the
35 number of measurements to take, valid values being 2 and 4.
36 - wlf,micd-timeout-ms : Timeout for microphone detection, specified in
38 - wlf,micd-force-micbias : Force MICBIAS continuously on during microphone
40 - wlf,micd-configs : Headset polarity configurations (generally used for
41 detection of CTIA / OMTP headsets), the field can be of variable length
42 but should always be a multiple of 3 cells long, each three cell group
43 represents one polarity configuration.
44 The first cell defines the accessory detection pin, zero will use MICDET1
45 and all other values will use MICDET2.
46 The second cell represents the MICBIAS to be used.
47 The third cell represents the value of the micd-pol-gpio pin.
49 - wlf,gpsw : Settings for the general purpose switch
