-Required properties:
-
-- compatible : should be "altr,timer-1.0"
-- reg : Specifies base physical address and size of the registers.
-- interrupts : Should contain the timer interrupt number
-- clock-frequency : The frequency of the clock that drives the counter, in Hz.

-Example:
-
-timer {
-	compatible = "altr,timer-1.0";
-	reg = <0x00400000 0x00000020>;
-	interrupt-parent = <&cpu>;
-	interrupts = <11>;
-	clock-frequency = <125000000>;
