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 : Must be one of: "st,stih407-lpc" "st,stih416-lpc"
13 "st,stih415-lpc" "st,stid127-lpc"
14 - reg : LPC registers base address + size
15 - interrupts : LPC interrupt line number and associated flags
16 - clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
17 - st,lpc-mode : The LPC can run either one of three modes:
20 ST_LPC_MODE_CLKSRC [2]
21 One (and only one) mode must be selected.
23 Required properties [watchdog mode]
25 - st,syscfg : Phandle to syscfg node used to enable watchdog and configure
27 - timeout-sec : Watchdog timeout in seconds
29 Optional properties [watchdog mode]
31 - st,warm-reset : If present reset type will be 'warm' - if not it will be cold
