+
+This DT node has pwrkey and resin as sub nodes.
+
+Required Properties:
+-compatible: "qcom,pm8916-pon"
+-reg: Specifies the physical address of the pon register
+
+Optional subnodes:
+-prwrkey: Specifies the subnode pwrkey and should follow the
+ qcom,pm8xxx-pwrkey.txt description.
+-resin: Specifies the subnode resin and should follow the
+ qcom,pm8xxx-pwrkey.txt description.
+
+The rest of the properties should follow the generic reboot-mode description
+found in reboot-mode.txt
+

+
+ reg = <0x800>;

+
+ pwrkey {
+ compatible = "qcom,pm8941-pwrkey";
+ interrupts = <0x0 0x8 0 IRQ_TYPE_EDGE_BOTH>;
+ debounce = <15625>;
+ bias-pull-up;
+ linux,code = <KEY_POWER>;
+ };
+
+ resin {
