+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@40000000 {
+ compatible = "arm,mps2-timer";
+ reg = <0x40000000 0x1000>;
+ interrupts = <8>;
+ clocks = <&sysclk>;
+};
+
+timer2: mps2-timer@40001000 {
+ compatible = "arm,mps2-timer";
+ reg = <0x40001000 0x1000>;
+ interrupts = <9>;
+ clock-frequency = <25000000>;
+};
