Altera Timer
Required properties:
- compatible : should be "altr,timer-1.0"
- reg : Specifies base physical address and size of the registers.
- interrupt-parent: phandle of the interrupt controller
- interrupts : Should contain the timer interrupt number
- clock-frequency : The frequency of the clock that drives the counter, in Hz.
Example:
timer {
compatible = "altr,timer-1.0";
reg = <0x00400000 0x00000020>;
interrupt-parent = <&cpu>;
interrupts = <11>;
clock-frequency = <125000000>;
};
