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-ms : Timeout for microphone detection, specified in milliseconds. - wlf,micd-force-micbias : Force MICBIAS continuously on during microphone detection. - wlf,micd-configs : Headset polarity configurations (generally used for detection of CTIA / OMTP headsets), the field can be of variable length but should always be a multiple of 3 cells long, each three cell group represents one polarity configuration. The first cell defines the accessory detection pin, zero will use MICDET1 and all other values will use MICDET2. The second cell represents the MICBIAS to be used. The third cell represents the value of the micd-pol-gpio pin. - wlf,gpsw : Settings for the general purpose switch, set as one of the ARIZONA_GPSW_XXX defines. Example: codec: wm8280@0 { compatible = "wlf,wm8280"; reg = <0>; ... wlf,use-jd2; wlf,use-jd2-nopull; wlf,jd-invert; wlf,micd-software-compare; wlf,micd-detect-debounce = <0>; wlf,micd-pol-gpio = <&codec 2 0>; wlf,micd-rate = ; wlf,micd-dbtime = <4>; wlf,micd-timeout-ms = <100>; wlf,micd-force-micbias; wlf,micd-configs = < 0 1 0 /* MICDET1 MICBIAS1 GPIO=low */ 1 2 1 /* MICDET2 MICBIAS2 GPIO=high */ >; wlf,gpsw = <0>; };
