ARC Timer
Required properties:
- compatible : should be "snps,arc-timer".
- reg : Specifies timer ID, could be either 0 or 1.
- clocks : Specifies clocks that drives the counter.
Examples:
timer@0 {
compatible = "snps,arc-timer";
clocks = <&core_clk>;
reg = <0>;
};
timer@1 {
compatible = "snps,arc-timer";
clocks = <&core_clk>;
reg = <1>;
};
NOTE: if you specify both timers, clocks always should be the same
as each timer is driven by the same core clock.
