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

		LPC currently supports Watchdog OR Real Time Clock functionality.
		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 one of: "st,stih407-lpc" "st,stih416-lpc"
		"st,stih415-lpc" "st,stid127-lpc"
		- 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 two modes ST_LPC_MODE_RTC [0] or
		ST_LPC_MODE_WDT [1]. One (and only one) mode must be
		selected.
		- 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 {
