+Marvell Armada 370 and Armada XP Timers
+---------------------------------------
+
+Required properties:
+- compatible: Should be one of the following
+              "marvell,armada-370-timer",
+	      "marvell,armada-375-timer",
+	      "marvell,armada-xp-timer".
+- interrupts: Should contain the list of Global Timer interrupts and
+  then local timer interrupts
+- reg: Should contain location and length for timers register. First
+  pair for the Global Timer registers, second pair for the
+  local/private timers.
+
+Clocks required for compatible = "marvell,armada-370-timer":
+- clocks : Must contain a single entry describing the clock input
+
+Clocks required for compatibles = "marvell,armada-xp-timer",
+				  "marvell,armada-375-timer":
+- 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).
+
+Examples:
+
+- Armada 370:
+
+	timer {
+		compatible = "marvell,armada-370-timer";
+		reg = <0x20300 0x30>, <0x21040 0x30>;
+		interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
+		clocks = <&coreclk 2>;
+	};
+
+- Armada XP:
+
+	timer {
+		compatible = "marvell,armada-xp-timer";
+		reg = <0x20300 0x30>, <0x21040 0x30>;
+		interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
+		clocks = <&coreclk 2>, <&refclk>;
+		clock-names = "nbclk", "fixed";
+	};
