-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>;
- };
- };
