-ARM MPS2 timer
-
-The MPS2 platform has simple general-purpose 32 bits timers.
-
-Required properties:
-- compatible	: Should be "arm,mps2-timer"
-- reg		: Address and length of the register set
-- interrupts	: Reference to the timer interrupt
-
-Required clocking property, have to be one of:
-- clocks	  : The input clock of the timer
-- clock-frequency : The rate in HZ in input of the ARM MPS2 timer
-
-Examples:
-
-timer1: mps2-timer@...00000 {
-	compatible = "arm,mps2-timer";
-	reg = <0x40000000 0x1000>;
-	interrupts = <8>;
-	clocks = <&sysclk>;
-};
-
-timer2: mps2-timer@...01000 {
-	compatible = "arm,mps2-timer";
-	reg = <0x40001000 0x1000>;
-	interrupts = <9>;
-	clock-frequency = <25000000>;
