 4LPC currently supports Watchdog OR Real Time Clock OR Clocksource
 5functionality.

10Required properties
11
12- compatible 	: Must 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.

22Example:
23	lpc@fde05000 {
24		compatible	= "st,stih407-lpc";
25		reg		= <0xfde05000 0x1000>;
26		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
27		st,lpc-mode	= <ST_LPC_MODE_RTC>;
28	};
