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,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,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>;
};
