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.yaml
properties:
wlf,hpdet-channel:
description:
Headphone detection channel. ARIZONA_ACCDET_MODE_HPL/1 sets the
headphone detect mode to HPDETL, ARIZONA_ACCDET_MODE_HPR/2 sets it
to HPDETR. If this node is not included or if the value is unknown,
then headphone detection mode is set to HPDETL.
