+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>;
+ };
