| - "renesas,r8a7743-wdt" (RZ/G1M) |
| - "renesas,r8a7744-wdt" (RZ/G1N) |
| - "renesas,r8a7745-wdt" (RZ/G1E) |
| - "renesas,r8a77470-wdt" (RZ/G1C) |
| - "renesas,r8a774a1-wdt" (RZ/G2M) |
| - "renesas,r8a774c0-wdt" (RZ/G2E) |
| - "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) |
| - "renesas,r7s9210-wdt" (RZ/A2) |
| 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>; |
| }; |
