STMicroelectronics Low Power Controller (LPC) - RTC
===================================================

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

[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
[See: ../timer/st,stih407-lpc for Clocksource options]

Required properties

- compatible 	: Must be: "st,stih407-lpc"
- reg		: LPC registers base address + size
- interrupts    : LPC interrupt line number and associated flags
- clocks	: Clock used by LPC device (See: ../clock/clock-bindings.txt)
- st,lpc-mode	: The LPC can run either one of three modes:
                  ST_LPC_MODE_RTC    [0]
                  ST_LPC_MODE_WDT    [1]
                  ST_LPC_MODE_CLKSRC [2]
		 One (and only one) mode must be selected.

Example:
	lpc@fde05000 {
		compatible	= "st,stih407-lpc";
		reg		= <0xfde05000 0x1000>;
		clocks 		= <&clk_s_d3_flexgen CLK_LPC_0>;
		st,lpc-mode	= <ST_LPC_MODE_RTC>;
	};
