1st and 2nd are ambiguous. Plus this is an OS implementation detail that 
doesn't belong in the binding.

+If you want to bind specific timer as clockevent (i.e. one from alive subsystem)
+and specific timer as clocksource, you can number the timers in "aliases" node.

No. 

Use and/or describe what are the features of a timer to make the 
decision. There has to be some reason you care which one. One has an 
interrupt and the other doesn't. One is always on. Etc.

Thank you, Rob.

Eventually I abandoned this decision.
I left only one patch, which you confirmed recently.

And sorry for making noise with duplicate patches.

Alexander.
