Interesting any known issues with or advantage over the arch timers
to prefer it as sched clock source. I see even arch timers are present
in DT, hence the question. Or is it just a incorrect commit log ?

How does this get selected as sched clock source ? I don't see
sched_clock_register in mtk_timer.c

To be clear, I am not against adding this timer support, but just want
to know is it preferred for sched clock source ? if yes why ? better
resolution ?

Missing documentation ? I am referring upstream and it might be in some 
patches already queued perhaps ?
