BCM2835 System Timer
|
|
|
|
The System Timer peripheral provides four 32-bit timer channels and a
|
|
single 64-bit free running counter. Each channel has an output compare
|
|
register, which is compared against the 32 least significant bits of the
|
|
free running counter values, and generates an interrupt.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "brcm,bcm2835-system-timer"
|
|
- reg : Specifies base physical address and size of the registers.
|
|
- interrupts : A list of 4 interrupt sinks; one per timer channel.
|
|
- clock-frequency : The frequency of the clock that drives the counter, in Hz.
|
|
|
|
Example:
|
|
|
|
timer {
|
|
compatible = "brcm,bcm2835-system-timer";
|
|
reg = <0x7e003000 0x1000>;
|
|
interrupts = <1 0>, <1 1>, <1 2>, <1 3>;
|
|
clock-frequency = <1000000>;
|
|
};
