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>;
};
};
};
