1 Renesas Watchdog Timer (WDT) Controller 2 3 Required properties: 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,r7s72100-wdt" (RZ/A1) 8 - "renesas,r8a7795-wdt" (R-Car H3) 9 - "renesas,r8a7796-wdt" (R-Car M3-W) 10 - "renesas,r8a77970-wdt" (R-Car V3M) 11 - "renesas,r8a77995-wdt" (R-Car D3) 12 13 When compatible with the generic version, nodes must list the SoC-specific 14 version corresponding to the platform first, followed by the generic 15 version. 16 17 - reg : Should contain WDT registers location and length 18 - clocks : the clock feeding the watchdog timer. 19 20 Optional properties: 21 - timeout-sec : Contains the watchdog timeout in seconds 22 - power-domains : the power domain the WDT belongs to 23 - interrupts: Some WDTs have an interrupt when used in interval timer mode 24 25 Examples: 26 27 wdt0: watchdog@e6020000 { 28 compatible = "renesas,r8a7795-wdt", "renesas,rcar-gen3-wdt"; 29 reg = <0 0xe6020000 0 0x0c>; 30 clocks = <&cpg CPG_MOD 402>; 31 power-domains = <&cpg>; 32 timeout-sec = <60>; 33 };
