+* Freescale i.MX System Controller Watchdog
+
+i.MX system controller watchdog is for i.MX SoCs with system controller inside,
+the watchdog is managed by system controller, users can ONLY communicate with
+system controller from secure mode for watchdog operations, so Linux i.MX system
+controller watchdog driver will call ARM SMC API and trap into ARM-Trusted-Firmware
+for watchdog operations, ARM-Trusted-Firmware is running at secure EL3 mode and
+it will request system controller to execute the watchdog operation passed from
+Linux kernel.
+
+Required properties:
+- compatible: Should be :
+ "fsl,imx8qxp-sc-wdt"
+ followed by "fsl,imx-sc-wdt";
+
+Optional properties:
+- timeout-sec : Contains the watchdog timeout in seconds.
+
+Examples:
+
+watchdog {
+ compatible = "fsl,imx8qxp-sc-wdt", "fsl,imx-sc-wdt";
+ timeout-sec = <60>;
+};
