+title: MT6359 Accessory Detection

+
+description:
+  The MT6359 Accessory Detection block is part of the MT6359 PMIC and allows
+  detecting audio jack insertion and removal, as well as identifying the type of
+  events connected to the jack.
+
+properties:
+  compatible:
+    const: mediatek,mt6359-accdet
+
+  mediatek,hp-eint-high:
+    type: boolean
+    description:
+      By default, MT6359's HP_EINT pin is assumed to be pulled high and
+      connected to a normally open 3.5mm jack. Plug insertion is detected when
+      the pin is brought low in that case. Add this property if the behavior
+      should be inverted, for example if a normally closed 3.5mm jack is used,
+      or if the line is pulled low on open.
+
+required:
+  - compatible
+
+additionalProperties: false
+
+examples:
+  - |
+    #include <dt-bindings/interrupt-controller/irq.h>
+
+    accdet: accdet {
+        compatible = "mediatek,mt6359-accdet";
+        mediatek,hp-eint-high;
+    };
