 Renesas Watchdog Timer (WDT) Controller
 
 Required properties:
-- compatible : Should be "renesas,<soctype>-wdt", and
-	       "renesas,rcar-gen3-wdt" or "renesas,rza-wdt" as fallback.
+ - compatible : Must be "renesas,<soctype>-wdt", followed by a generic
+		fallback compatible string when compatible with the generic
+		version.
 	       Examples with soctypes are:
+		 - "renesas,r8a7743-wdt" (RZ/G1M)
+		 - "renesas,r8a7745-wdt" (RZ/G1E)
 	         - "renesas,r8a7795-wdt" (R-Car H3)
 	         - "renesas,r8a7796-wdt" (R-Car M3-W)
 	         - "renesas,r8a77995-wdt" (R-Car D3)
 	         - "renesas,r7s72100-wdt" (RZ/A1)
+		The generic compatible string must be:
+		 - "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G
+		 - "renesas,rcar-gen3-wdt" for R-Car Gen3
 
-  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.
