For "marvell,armada-375-wdt" and "marvell,armada-380-wdt": - reg : A third entry is mandatory and should contain the shared mask/unmask RSTOUT address. Clocks required for compatibles = "marvell,orion-wdt", "marvell,armada-370-wdt": - clocks : Must contain a single entry describing the clock input Clocks required for compatibles = "marvell,armada-xp-wdt" "marvell,armada-375-wdt" "marvell,armada-380-wdt": - clocks : Must contain an entry for each entry in clock-names. - clock-names : Must include the following entries: "nbclk" (L2/coherency fabric clock), "fixed" (Reference 25 MHz fixed-clock). Optional properties: - interrupts : Contains the IRQ for watchdog expiration - timeout-sec : Contains the watchdog timeout in seconds Example: wdt@20300 { compatible = "marvell,orion-wdt"; reg = <0x20300 0x28>, <0x20108 0x4>; interrupts = <3>; timeout-sec = <10>; clocks = <&gate_clk 7>; }; |
