+STMicroelectronics LPC Watchdog
+===============================
+
+Required properties
+
+- compatible : Must be one of:
+ "st,stih407-watchdog"
+ "st,stih416-watchdog"
+ "st,stih415-watchdog"
+ "st,stid127-watchdog"
+- reg : LPC registers base address + size
+- reg-names : Register map "base" and "syscfg-en" are compulsory.
+ "syscfg-type" is platform dependent and not required for the
+ STiH407
+- clock-names : Should be "lpc_wdt"
+- clocks : Clock used by LPC device
+- timeout-sec : Watchdog 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@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;
+ };
