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";
	};
