Kernel-4.18.0-80.el8_fsl-imx-wdt

• Freescale i.MX Watchdog Timer (WDT) Controller

Required properties:

• compatible : Should be “fsl,-wdt”
• reg : Should contain WDT registers location and length
• interrupts : Should contain WDT interrupt

Optional properties:

• big-endian: If present the watchdog device’s registers are implemented
  in big endian mode, otherwise in native mode(same with CPU), for more
  detail please see: Documentation/devicetree/bindings/regmap/regmap.txt.
• fsl,ext-reset-output: If present the watchdog device is configured to
  assert its external reset (WDOG_B) instead of issuing a software reset.
• timeout-sec : Contains the watchdog timeout in seconds

Examples:

wdt@73f98000 {
compatible = “fsl,imx51-wdt”, “fsl,imx21-wdt”;
reg = <0x73f98000 0x4000>;
interrupts = <58>;
big-endian;
timeout-sec = <20>;
};
