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.
