AM33XX has only one usable timer in the WKUP domain.
Currently the timer instance in WKUP domain is used
as the clockevent and the timer in non-WKUP domain
as the clocksource. The timer in WKUP domain can keep
running in suspend from a 32K clock and hence serve
as the persistent clock. To enable this, interchange
the timers used as clocksource and clockevent for
AM33XX.
Doesn't this also mean that you won't get timer wakeups
in idle? Or are you keeping the domain where the clockevent is
on during idle?
The lowest idle state that we are targeting will have MPU powered
off with external memory in self-refresh mode. Peripheral domain
with the clockevent will be kept on.
Is this a limitation of the hardware? or the software?

P.S. I haven't yet made my way through the TRM, so I'll probably figure
this out when I read it, but having this summarized in the changelog would
be helpful since even after I read the TRM, I'll forget. I'm saving the
TRM
reading for entertainment on upcoming flight home from Linaro Connect.
