Hi,
I'm trying to use clocksource and clockevent new subsystem. My platform has a timer that I'd like to use both as a clocksource and a clockevent devices. This timer is continueous in sense that it can run without any interruption so I assume I can flag the clocksource device with "CLOCK_SOURCE_IS_CONTINUOUS". However I noticed that clockevent device can be stopped by using "set_mode()" method. Are these two behaviours compatible ?
Another question is that I have another embedded 16 bits timer that I would like to use. Since the timer is only 16 bits, the maximum interval is tiny, My question if a user ask for a clockevent device using an interval is bigger that 2^16, the clockevent system doesn't return an error. Instead it silently reduce the interval to 2^16. Is this correct ? if so why ?
