We can rephrase it to : " If the mtime/time increments past the watchdog stage 2 compare value then a system reset shall occur"

We can rephrase it to "If the mtime/time increments past the watchdog stage 2 compare value then a system reset shall occur". This leaves open the question of how and when the reset will occur while r

I am planning to add an implementation note in the next version of the patch which will provide more details about how the software can use it. Thanks, Mayuresh.

This property is defined in the cpus node for riscv: https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/riscv/cpus.yaml. We can refer to this in the platform spec.

It refers to the hardware clock which is used to drive the counter and not the RTC.

Yes, currently the details for ACPI are TBD and so it is not included in the patch.

Thanks, Mayuresh. Based on the discussion earlier, I thought this would be a separate spec. But it does not overlap with the other text in that section. Do we need to refer to CLINT? Would it suffice

Actually these are different requirements. From the software perspective the counter is required to have atleast 10 ns resolution. But the hardware clock that drives the counter is expected to run at
