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,r8a7745-rst" (RZ/G1E)
    - "renesas,r8a77470-rst" (RZ/G1C)
    - "renesas,r8a7778-reset-wdt" (R-Car M1A)
    - "renesas,r8a7779-reset-wdt" (R-Car H1)
    - "renesas,r8a7790-rst" (R-Car H2)
    - "renesas,r8a7791-rst" (R-Car M2-W)
    - "renesas,r8a7792-rst" (R-Car V2H
    - "renesas,r8a7793-rst" (R-Car M2-N)
    - "renesas,r8a7794-rst" (R-Car E2)
    - "renesas,r8a7795-rst" (R-Car H3)
    - "renesas,r8a7796-rst" (R-Car M3-W)
    - "renesas,r8a77965-rst" (R-Car M3-N)
    - "renesas,r8a77970-rst" (R-Car V3M)
    - "renesas,r8a77980-rst" (R-Car V3H)
    - "renesas,r8a77990-rst" (R-Car E3)
    - "renesas,r8a77995-rst" (R-Car D3)
  

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

Example:

rst: reset-controller@e6160000 {
    compatible = "renesas,r8a7795-rst";
    reg = <0 0xe6160000 0 0x0200>;
};
