Basic PM support for 83xx. Standby is implemented as sleep.
Suspend-to-RAM is implemented as "deep sleep" (with the processor

Device power management of SOC peripherals is not yet supported.

Do you know if anyone is looking at making sure DOZE/NAP work on 83xx?
We clearly don't flush the L1 cache today in the 6xx code.
Doze should work (a long time ago when I did power measurements I saw a
drop in consumption once Linux started, and the system was idle)... Nap
is not supported, and should probably be removed from the e300 cputable
entry. I don't think it's worthwhile to flush the cache every time the
cpu is idle just to nap instead of doze.
