The idea breaking PM seems silly to me considering that we've
had
it working for years already.

Same question  / note. World is much more complex than just
being OMAP.

Sorry but you are making assumptions about hardware being powered
on
all the time.

Nope, other way around. The so called "support" _prevents_ our
hardware to go to sleep.

Hmm sorry now I'm all confused what issues you're having.

I thought you said earlier the issue was that you wanted to keep
the console enabled all the time and never idle?

Yes, for kernel console.
To be clear, if user supplies "console=ttySx" it keeps powered on
always. But if there is no such parameter, we are fine with RPM.

Letting kernel console do power management on the systems without
irq_safe hack is dangerous in terms of loosing important data (crash, or
some other stuff which needs atomic context: kgdb?).
