1BCM2835 System Timer
2
3The System Timer peripheral provides four 32-bit timer channels and a
4single 64-bit free running counter. Each channel has an output compare
5register, which is compared against the 32 least significant bits of the
6free running counter values, and generates an interrupt.
7
8Required properties:
9
10- compatible : should be "brcm,bcm2835-system-timer.txt"
11- reg : Specifies base physical address and size of the registers.
12- interrupts : A list of 4 interrupt sinks; one per timer channel.
13- clock-frequency : The frequency of the clock that drives the counter, in Hz.
14
15Example:
16
17timer {
18 compatible = "brcm,bcm2835-system-timer";
19 reg = <0x7e003000 0x1000>;
20 interrupts = <1 0>, <1 1>, <1 2>, <1 3>;
21 clock-frequency = <1000000>;
22};
