-DT bindings for the Renesas R-Car and RZ/G Reset Controllers
-
-The R-Car and RZ/G Reset Controllers provide reset control, and implement the
-following functions:
-  - Latching of the levels on mode pins when PRESET# is negated,
-  - Mode monitoring register,
-  - Reset control of peripheral devices (on R-Car Gen1),
-  - Watchdog timer (on R-Car Gen1),
-  - Register-based reset control and boot address registers for the various CPU
-    cores (on R-Car Gen2 and Gen3, and on RZ/G).
-
-
-Required properties:
-  - compatible: Should be
-		  - "renesas,<soctype>-reset-wdt" for R-Car Gen1,
-		  - "renesas,<soctype>-rst" for R-Car Gen2 and Gen3, and RZ/G
-		Examples with soctypes are:
-		  - "renesas,r8a7743-rst" (RZ/G1M)
-		  - "renesas,r8a7744-rst" (RZ/G1N)
-		  - "renesas,r8a7745-rst" (RZ/G1E)

-		  - "renesas,r8a774c0-rst" (RZ/G2E)
-		  - "renesas,r8a7778-reset-wdt" (R-Car M1A)
-		  - "renesas,r8a7779-reset-wdt" (R-Car H1)
-		  - "renesas,r8a7790-rst" (R-Car H2)

-  - reg: Address start and address range for the device.
