1 Renesas Watchdog Timer (WDT) Controller
4 - compatible : Should be "renesas,<soctype>-wdt", and
5 "renesas,rcar-gen3-wdt" or "renesas,rza-wdt" as fallback.
6 Examples with soctypes are:
7 - "renesas,r8a7795-wdt" (R-Car H3)
8 - "renesas,r8a7796-wdt" (R-Car M3-W)
9 - "renesas,r8a77995-wdt" (R-Car D3)
10 - "renesas,r7s72100-wdt" (RZ/A1)
12 When compatible with the generic version, nodes must list the SoC-specific
13 version corresponding to the platform first, followed by the generic
16 - reg : Should contain WDT registers location and length
17 - clocks : the clock feeding the watchdog timer.
20 - timeout-sec : Contains the watchdog timeout in seconds
21 - power-domains : the power domain the WDT belongs to
22 - interrupts: Some WDTs have an interrupt when used in interval timer mode
