1 | BCM2835 System Timer | ||
2 | |||
3 | The System Timer peripheral provides four 32-bit timer channels and a | ||
4 | single 64-bit free running counter. Each channel has an output compare | ||
5 | register, which is compared against the 32 least significant bits of the | ||
6 | free running counter values, and generates an interrupt. | ||
7 | |||
8 | Required 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 | |||
15 | Example: | ||
16 | |||
17 | timer { | ||
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 | }; | ||
