-* Marvell MMP Timer controller

-Required properties:
-- compatible : Should be "mrvl,mmp-timer".
-- reg : Address and length of the register set of timer controller.
-- interrupts : Should be the interrupt number.
-
-Optional properties:
-- clocks : Should contain a single entry describing the clock input.

-Example:
-	timer0: timer@...14000 {
-		compatible = "mrvl,mmp-timer";
-		reg = <0xd4014000 0x100>;
-		interrupts = <13>;
-		clocks = <&coreclk 2>;
