1 STMicroelectronics Low Power Controller (LPC) - Watchdog
2 ========================================================
4 LPC currently supports Watchdog OR Real Time Clock functionality.
6 [See: ../rtc/rtc-st-lpc.txt for RTC options]
10 - compatible : Must be one of: "st,stih407-lpc" "st,stih416-lpc"
11 "st,stih415-lpc" "st,stid127-lpc"
12 - reg : LPC registers base address + size
13 - interrupts : LPC interrupt line number and associated flags
14 - clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
15 - st,lpc-mode : The LPC can run either one of two modes ST_LPC_MODE_RTC [0] or
16 ST_LPC_MODE_WDT [1]. One (and only one) mode must be
19 Required properties [watchdog mode]
21 - st,syscfg : Phandle to syscfg node used to enable watchdog and configure
23 - timeout-sec : Watchdog timeout in seconds
25 Optional properties [watchdog mode]
27 - st,warm-reset : If present reset type will be 'warm' - if not it will be cold
