+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.
