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_CLKSRC>;
28       };
