rtc: bindings: Provide ST bindings for ST's LPC RTC device 



On current ST platforms the LPC controls a number of functions including
Watchdog and Real Time Clock.  This patch provides the bindings used to
configure LPC in RTC mode.

STMicroelectronics Low Power Controller (LPC) - RTC

===================================================



LPC currently supports Watchdog OR Real Time Clock functionality.



[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]



Required properties



- compatible 	: Must be one of: "st,stih407-lpc" "st,stih416-lpc"

				  "st,stih415-lpc" "st,stid127-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.



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>;

	};
