| Renesas Watchdog Timer (WDT) Controller |
| |
| Required properties: |
| - compatible : Should be "renesas,<soctype>-wdt", and |
| "renesas,rcar-gen3-wdt" or "renesas,rza-wdt" as fallback. |
| Examples with soctypes are: |
| - "renesas,r7s72100-wdt" (RZ/A1) |
| - "renesas,r8a7795-wdt" (R-Car H3) |
| - "renesas,r8a7796-wdt" (R-Car M3-W) |
| - "renesas,r8a77970-wdt" (R-Car V3M) |
| - "renesas,r8a77995-wdt" (R-Car D3) |
| |
| When compatible with the generic version, nodes must list the SoC-specific |
| version corresponding to the platform first, followed by the generic |
| version. |
| |
| - 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>; |
| }; |
