-* NXP LPC18xx Watchdog Timer (WDT)
-
-Required properties:
-- compatible: Should be "nxp,lpc1850-wwdt"
-- reg: Should contain WDT registers location and length
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Should contain "wdtclk" and "reg"; the watchdog counter
- clock and register interface clock respectively.
-- interrupts: Should contain WDT interrupt
-
-Examples:
-
-watchdog@40080000 {
- compatible = "nxp,lpc1850-wwdt";
- reg = <0x40080000 0x24>;
- clocks = <&cgu BASE_SAFE_CLK>, <&ccu1 CLK_CPU_WWDT>;
- clock-names = "wdtclk", "reg";
- interrupts = <49>;
-};
