+STMicroelectronics LPC Watchdog
+===============================
+
+Required properties
+
+- compatible 	: "st,<soc>-watchdog"
+- reg		: LPC registers base address + range
+- reg-names	: Register map "base" and "syscfg-en" are compulsory "type" is
+		  platform dependent and not required for the STiH407.
+- clock-names 	: Should be "lpc_wdt"
+- clocks	: Clock used by LPC device
+- timeout-sec	: Qatchdog timeout in seconds
+- st,syscfg	: Syscfg node used to configure cpu reset type and mask
+- st,warm_reset	: If present, reset type will be 'warm'. If not, it will be cold
+
+Example:
+	watchdog at fde05000 {
+		compatible	= "st,stih416-lpc-watchdog";
+		reg		= <0xfde05000 0x1000> <0x204 0x4>;
+		reg-names	= "base", "syscfg-en"
+		clock-names	= "lpc_wdt";
+		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
+		timeout-sec	= <600>;
+		st,syscfg	= <&syscfg_core>;
+		st,warm_reset;
+	};
