Renesas Watchdog Timer (WDT) Controller Required properties: - compatible : Must be "renesas,-wdt", followed by a generic fallback compatible string when compatible with the generic version. Examples with soctypes are: - "renesas,r8a7743-wdt" (RZ/G1M) - "renesas,r8a7744-wdt" (RZ/G1N) - "renesas,r8a7745-wdt" (RZ/G1E) - "renesas,r8a774a1-wdt" (RZ/G2M) - "renesas,r8a7790-wdt" (R-Car H2) - "renesas,r8a7791-wdt" (R-Car M2-W) - "renesas,r8a7792-wdt" (R-Car V2H) - "renesas,r8a7793-wdt" (R-Car M2-N) - "renesas,r8a7794-wdt" (R-Car E2) - "renesas,r8a7795-wdt" (R-Car H3) - "renesas,r8a7796-wdt" (R-Car M3-W) - "renesas,r8a77965-wdt" (R-Car M3-N) - "renesas,r8a77970-wdt" (R-Car V3M) - "renesas,r8a77990-wdt" (R-Car E3) - "renesas,r8a77995-wdt" (R-Car D3) - "renesas,r7s72100-wdt" (RZ/A1) The generic compatible string must be: - "renesas,rza-wdt" for RZ/A - "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G1 - "renesas,rcar-gen3-wdt" for R-Car Gen3 and RZ/G2 - reg : Should contain WDT registers location and length - clocks : the clock feeding the watchdog timer. Optional properties: - timeout-sec : Contains the watchdog timeout in seconds - power-domains : the power domain the WDT belongs to - interrupts: Some WDTs have an interrupt when used in interval timer mode Examples: wdt0: watchdog@e6020000 { compatible = "renesas,r8a7795-wdt", "renesas,rcar-gen3-wdt"; reg = <0 0xe6020000 0 0x0c>; clocks = <&cpg CPG_MOD 402>; power-domains = <&cpg>; timeout-sec = <60>; };
