1 Renesas Watchdog Timer (WDT) Controller
4 - compatible : Must be "renesas,<soctype>-wdt", followed by a generic
5 fallback compatible string when compatible with the generic
7 Examples with soctypes are:
8 - "renesas,r8a7743-wdt" (RZ/G1M)
9 - "renesas,r8a7745-wdt" (RZ/G1E)
10 - "renesas,r8a774a1-wdt" (RZ/G2M)
11 - "renesas,r8a7790-wdt" (R-Car H2)
12 - "renesas,r8a7791-wdt" (R-Car M2-W)
13 - "renesas,r8a7792-wdt" (R-Car V2H)
14 - "renesas,r8a7793-wdt" (R-Car M2-N)
15 - "renesas,r8a7794-wdt" (R-Car E2)
16 - "renesas,r8a7795-wdt" (R-Car H3)
17 - "renesas,r8a7796-wdt" (R-Car M3-W)
18 - "renesas,r8a77965-wdt" (R-Car M3-N)
19 - "renesas,r8a77970-wdt" (R-Car V3M)
20 - "renesas,r8a77990-wdt" (R-Car E3)
21 - "renesas,r8a77995-wdt" (R-Car D3)
22 - "renesas,r7s72100-wdt" (RZ/A1)
23 The generic compatible string must be:
24 - "renesas,rza-wdt" for RZ/A
25 - "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G1
26 - "renesas,rcar-gen3-wdt" for R-Car Gen3 and RZ/G2
28 - reg : Should contain WDT registers location and length
29 - clocks : the clock feeding the watchdog timer.
32 - timeout-sec : Contains the watchdog timeout in seconds
33 - power-domains : the power domain the WDT belongs to
34 - interrupts: Some WDTs have an interrupt when used in interval timer mode
