| 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,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 |
