1 Synopsys ARC Local Timer with Interrupt Capabi
2 - Found on all ARC CPUs (ARC700/ARCHS)
3 - Can be optionally programmed to interrupt on
4 - Two identical copies TIMER0 and TIMER1 exist
5 TIMER0 used as clockevent provider (true for
6 TIMER1 used for clocksource (mandatory for A
7
8 Required properties:
9
10 - compatible : should be "snps,arc-timer"
11 - interrupts : single Interrupt going into par
12 (16 for ARCHS cores, 3 for ARC7
13 - clocks : phandle to the source clock
14
15 Example:
16
17 timer0 {
18 compatible = "snps,arc-timer";
19 interrupts = <3>;
20 interrupt-parent = <&core_intc
21 clocks = <&core_clk>;
22 };
23
24 timer1 {
25 compatible = "snps,arc-timer";
26 clocks = <&core_clk>;
27 };
