-* Marvell Orion Watchdog Time
-
-Required Properties:
-
-- Compatibility : "marvell,orion-wdt"
- "marvell,armada-370-wdt"
- "marvell,armada-xp-wdt"
- "marvell,armada-375-wdt"
- "marvell,armada-380-wdt"
-
-- reg : Should contain two entries: first one with the
- timer control address, second one with the
- rstout enable address.
-
-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>;
- };
