1 STMicroelectronics Low Power Controller (LPC) - Watchdog
2 ========================================================
4 LPC currently supports Watchdog OR Real Time Clock OR Clocksource
7 [See: ../rtc/rtc-st-lpc.txt for RTC options]
8 [See: ../timer/st,stih407-lpc for Clocksource options]
12 - compatible : Should 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:
19 ST_LPC_MODE_CLKSRC [2]
20 One (and only one) mode must be selected.
22 Required properties [watchdog mode]
24 - st,syscfg : Phandle to syscfg node used to enable watchdog and configure
26 - timeout-sec : Watchdog timeout in seconds
28 Optional properties [watchdog mode]
30 - st,warm-reset : If present reset type will be 'warm' - if not it will be cold
