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>;
};
