Renesas Watchdog Timer (WDT) Controller
|
|
|
|
Required properties:
|
|
- compatible : Must be "renesas,<soctype>-wdt", followed by a generic
|
|
fallback compatible string when compatible with the generic
|
|
version.
|
|
Examples with soctypes are:
|
|
- "renesas,r8a7743-wdt" (RZ/G1M)
|
|
- "renesas,r8a7744-wdt" (RZ/G1N)
|
|
- "renesas,r8a7745-wdt" (RZ/G1E)
|
|
- "renesas,r8a774a1-wdt" (RZ/G2M)
|
|
- "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,r8a77990-wdt" (R-Car E3)
|
|
- "renesas,r8a77995-wdt" (R-Car D3)
|
|
- "renesas,r7s72100-wdt" (RZ/A1)
|
|
- "renesas,r7s9210-wdt" (RZ/A2)
|
|
The generic compatible string must be:
|
|
- "renesas,rza-wdt" for RZ/A
|
|
- "renesas,rcar-gen2-wdt" for R-Car Gen2 and RZ/G1
|
|
- "renesas,rcar-gen3-wdt" for R-Car Gen3 and RZ/G2
|
|
|
|
- reg : Should contain WDT registers location and length
|
|
- clocks : the clock feeding the watchdog timer.
|
|
|
|
Optional properties:
|
|
- timeout-sec : Contains the watchdog timeout in seconds
|
|
- power-domains : the power domain the WDT belongs to
|
|
- interrupts: Some WDTs have an interrupt when used in interval timer mode
|
|
|
|
Examples:
|
|
|
|
wdt0: watchdog@e6020000 {
|
|
compatible = "renesas,r8a7795-wdt", "renesas,rcar-gen3-wdt";
|
|
reg = <0 0xe6020000 0 0x0c>;
|
|
clocks = <&cpg CPG_MOD 402>;
|
|
power-domains = <&cpg>;
|
|
timeout-sec = <60>;
|
|
};
