+
+This pm8916 watchdog timer controller must be under pm8916-pon node.
+
+Required properties:

+
+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>;
+			};
