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,r8a77470-rst" (RZ/G1C)

		  - "renesas,r8a774a1-rst" (RZ/G2M)

		  - "renesas,r8a774b1-rst" (RZ/G2N)

		  - "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)

		  - "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,r8a77961-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>;
