-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>;
-};
