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

8[See: ../timer/st,stih407-lpc for Clocksource options]

10Required properties
11
12- compatible 	: Should be: "st,stih407-lpc"
13- reg		: LPC registers base address + size
14- interrupts    : LPC interrupt line number and associated flags
15- clocks	: Clock used by LPC device (See: ../clock/clock-bindings.txt)
16- st,lpc-mode	: The LPC can run either one of three modes:
17                  ST_LPC_MODE_RTC    [0]
18                  ST_LPC_MODE_WDT    [1]
19                  ST_LPC_MODE_CLKSRC [2]
20		 One (and only one) mode must be selected.
21
22Required properties [watchdog mode]
23
24- st,syscfg	: Phandle to syscfg node used to enable watchdog and configure
25		  CPU reset type.
26- timeout-sec	: Watchdog timeout in seconds
27
28Optional properties [watchdog mode]
29
30- st,warm-reset	: If present reset type will be 'warm' - if not it will be cold
31
32Example:
33	lpc@fde05000 {
34		compatible	= "st,stih407-lpc";
35		reg		= <0xfde05000 0x1000>;
36		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
37		st,syscfg	= <&syscfg_core>;
38		timeout-sec	= <120>;
39		st,lpc-mode	= <ST_LPC_MODE_WDT>;
40		st,warm-reset;
41	};
