1STMicroelectronics Low Power Controller (LPC) - Watchdog
2========================================================
3
4LPC currently supports Watchdog OR Real Time Clock OR Clocksource
5functionality.

10Required properties
11
12- compatible 	: Must be one of: "st,stih407-lpc" "st,stih416-lpc"
13				  "st,stih415-lpc" "st,stid127-lpc"
14- reg		: LPC registers base address + size
15- interrupts    : LPC interrupt line number and associated flags
16- clocks	: Clock used by LPC device (See: ../clock/clock-bindings.txt)
17- st,lpc-mode	: The LPC can run either one of three modes:
18                  ST_LPC_MODE_RTC    [0]
19                  ST_LPC_MODE_WDT    [1]
20                  ST_LPC_MODE_CLKSRC [2]
21		 One (and only one) mode must be selected.
22
23Required properties [watchdog mode]
24
25- st,syscfg	: Phandle to syscfg node used to enable watchdog and configure
26		  CPU reset type.
27- timeout-sec	: Watchdog timeout in seconds
28
29Optional properties [watchdog mode]
30
31- st,warm-reset	: If present reset type will be 'warm' - if not it will be cold

33Example:
34	lpc@fde05000 {
35		compatible	= "st,stih407-lpc";
36		reg		= <0xfde05000 0x1000>;
37		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
38		st,syscfg	= <&syscfg_core>;
39		timeout-sec	= <120>;
40		st,lpc-mode	= <ST_LPC_MODE_WDT>;
41		st,warm-reset;
42	};
