-* Freescale i.MX7ULP Watchdog Timer (WDT) Controller
-
-Required properties:
-- compatible : Should be "fsl,imx7ulp-wdt"
-- reg : Should contain WDT registers location and length
-- interrupts : Should contain WDT interrupt
-- clocks: Should contain a phandle pointing to the gated peripheral clock.
-
-Optional properties:
-- timeout-sec : Contains the watchdog timeout in seconds
-
-Examples:
-
-wdog1: watchdog@403d0000 {
- compatible = "fsl,imx7ulp-wdt";
- reg = <0x403d0000 0x10000>;

- clocks = <&pcc2 IMX7ULP_CLK_WDG1>;
- assigned-clocks = <&pcc2 IMX7ULP_CLK_WDG1>;
- assigned-clocks-parents = <&scg1 IMX7ULP_CLK_FIRC_BUS_CLK>;
- timeout-sec = <40>;
