1 Synopsys ARC Local Timer with Interrupt Capabilities
2 - Found on all ARC CPUs (ARC700/ARCHS)
3 - Can be optionally programmed to interrupt on Limit
4 - Two idential copies TIMER0 and TIMER1 exist in ARC cores and historically
5 TIMER0 used as clockevent provider (true for all ARC cores)
6 TIMER1 used for clocksource (mandatory for ARC700, optional for ARC HS)
10 - compatible : should be "snps,arc-timer"
11 - interrupts : single Interrupt going into parent intc
12 (16 for ARCHS cores, 3 for ARC700 cores)
13 - clocks : phandle to the source clock
17 - interrupt-parent : phandle to parent intc
