2 | ||
3 | Required properties: | |
c682b5cb | 4 | - compatible : Should be "renesas,<soctype>-wdt", and |
0ab13808 | 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) | |
0ab13808 | 9 | - "renesas,r7s72100-wdt" (RZ/A1) |

11 | When compatible with the generic version, nodes must list the SoC-specific | |
12 | version corresponding to the platform first, followed by the generic | |
13 | version. | |
14 | ||
15 | - reg : Should contain WDT registers location and length | |
16 | - clocks : the clock feeding the watchdog timer. | |
17 | ||
18 | Optional properties: | |
19 | - timeout-sec : Contains the watchdog timeout in seconds | |
20 | - power-domains : the power domain the WDT belongs to | |
0ab13808 | 21 | - interrupts: Some WDTs have an interrupt when used in interval timer mode |
