| Synopsys ARC Local Timer with Interrupt Capabilities |
| - Found on all ARC CPUs (ARC700/ARCHS) |
| - Can be optionally programmed to interrupt on Limit |
| - Two idential copies TIMER0 and TIMER1 exist in ARC cores and historically |
| TIMER0 used as clockevent provider (true for all ARC cores) |
| TIMER1 used for clocksource (mandatory for ARC700, optional for ARC HS) |
| |
| Required properties: |
| |
| - compatible : should be "snps,arc-timer" |
| - interrupts : single Interrupt going into parent intc |
| (16 for ARCHS cores, 3 for ARC700 cores) |
| - clocks : phandle to the source clock |
| |
| Example: |
| |
| timer0 { |
| compatible = "snps,arc-timer"; |
| interrupts = <3>; |
| interrupt-parent = <&core_intc>; |
| clocks = <&core_clk>; |
| }; |
| |
| timer1 { |
| compatible = "snps,arc-timer"; |
| clocks = <&core_clk>; |
| }; |
