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>;

			};

		};

	};
