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>;
|
|
};
