3Required properties:
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,r8a7744-wdt" (RZ/G1N)
10		 - "renesas,r8a7745-wdt" (RZ/G1E)
11		 - "renesas,r8a77470-wdt" (RZ/G1C)
12		 - "renesas,r8a774a1-wdt" (RZ/G2M)
13		 - "renesas,r8a774c0-wdt" (RZ/G2E)
14	         - "renesas,r8a7790-wdt" (R-Car H2)
15	         - "renesas,r8a7791-wdt" (R-Car M2-W)
16	         - "renesas,r8a7792-wdt" (R-Car V2H)
17	         - "renesas,r8a7793-wdt" (R-Car M2-N)
18	         - "renesas,r8a7794-wdt" (R-Car E2)
19	         - "renesas,r8a7795-wdt" (R-Car H3)
20	         - "renesas,r8a7796-wdt" (R-Car M3-W)
21		 - "renesas,r8a77965-wdt" (R-Car M3-N)
22	         - "renesas,r8a77970-wdt" (R-Car V3M)
23	         - "renesas,r8a77990-wdt" (R-Car E3)
24	         - "renesas,r8a77995-wdt" (R-Car D3)
25	         - "renesas,r7s72100-wdt" (RZ/A1)
26	         - "renesas,r7s9210-wdt"  (RZ/A2)
27		The generic compatible string must be:
28		 - "renesas,rza-wdt" for RZ/A
29		 - "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G1
30		 - "renesas,rcar-gen3-wdt" for R-Car Gen3 and RZ/G2
31
32- reg : Should contain WDT registers location and length
33- clocks : the clock feeding the watchdog timer.
34
35Optional properties:
36- timeout-sec : Contains the watchdog timeout in seconds
37- power-domains : the power domain the WDT belongs to
38- interrupts: Some WDTs have an interrupt when used in interval timer mode

41
42	wdt0: watchdog@e6020000 {
43		compatible = "renesas,r8a7795-wdt", "renesas,rcar-gen3-wdt";
44		reg = <0 0xe6020000 0 0x0c>;
45		clocks = <&cpg CPG_MOD 402>;
46		power-domains = <&cpg>;
47		timeout-sec = <60>;
