dt-bindings: watchdog: renesas-wdt: Add R-Car Gen2 support 



This commit documents the compatibility with R-Car Gen2 and RZ/G
devices by defining the generic compatible string "renesas,rcar-gen2-wdt".
Also, this patch expands the list of SoC-specific compatible strings to
include RZ/G and R-Car Gen2 devices.

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,r7s72100-wdt" (RZ/A1)

		 - "renesas,r8a7743-wdt" (RZ/G1M)

		 - "renesas,r8a7745-wdt" (RZ/G1E)

	         - "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,r8a77995-wdt" (R-Car D3)



  When compatible with the generic version, nodes must list the SoC-specific

  version corresponding to the platform first, followed by the generic

  version.

	         - "renesas,r7s72100-wdt" (RZ/A1)

		The generic compatible string must be:

		 - "renesas,rza-wdt" for RZ/A

		 - "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G

		 - "renesas,rcar-gen3-wdt" for R-Car Gen3



- reg : Should contain WDT registers location and length

- clocks : the clock feeding the watchdog timer.
