    1 ARM MPS2 timer
    2 
    3 The MPS2 platform has simple general-purpose 32 bits timers.
    4 
    5 Required properties:
    6 - compatible    : Should be "arm,mps2-timer"
    7 - reg           : Address and length of the register set
    8 - interrupts    : Reference to the timer interrupt
    9 
   10 Required clocking property, have to be one of:
   11 - clocks          : The input clock of the timer
   12 - clock-frequency : The rate in HZ in input of the ARM MPS2 timer
   13 
   14 Examples:
   15 
   16 timer1: mps2-timer@40000000 {
   17         compatible = "arm,mps2-timer";
   18         reg = <0x40000000 0x1000>;
   19         interrupts = <8>;
   20         clocks = <&sysclk>;
   21 };
   22 
   23 timer2: mps2-timer@40001000 {
   24         compatible = "arm,mps2-timer";
   25         reg = <0x40001000 0x1000>;
   26         interrupts = <9>;
   27         clock-frequency = <25000000>;
   28 };
