+QCOM PM8916 watchdog timer controller
+
+This pm8916 watchdog timer controller must be under pm8916-pon node.
+
+Required properties:
+- compatible: should be "qcom,pm8916-wdt"
+
+Optional properties :
+- interrupts : Watchdog pre-timeout (bark) interrupt.
+- timeout-sec : Watchdog timeout value in seconds.
+
+Example:
+
+ pm8916_0: pm8916@0 {
+ compatible = "qcom,pm8916", "qcom,spmi-pmic";
+ reg = <0x0 SPMI_USID>;
+
+ pon@800 {
+ compatible = "qcom,pm8916-pon";
+ reg = <0x800>;
+
+ watchdog {
+ compatible = "qcom,pm8916-wdt";
+ interrupts = <0x0 0x8 6 IRQ_TYPE_EDGE_RISING>;
+ timeout-sec = <10>;
+ };
+ };
+ };
