So this is the only patch in this series that is still needed. However...
It doesn't seem like this all by itself is ready for mainline as we'll
suddenly start putting all powerdomains in retention without any
additional support.
I guess at a minimum it needs working IO wakeup support from the IO
daisy chain series. Are there other dependencies here?
Only IO chain is needed for wakeup capability. Actually even with the
current mainline kernel, I am unable to wake-up the device from MPU
retention, as there are no wakeup sources. So this patch doesn't really
Why?, doesn't debug console wakeup work?
change the behavior to worse even without any additional patches. :) But
yea, good to wait until IO chain is in.
IO chain, according to documentation :) should be needed only if you
hit OSWR or OFF, async wakeups should be functional as long as you
only hit CSWR.
The other dependencies are that the stuff handled by patches 2,3 and 4
have to be handled somehow:
-patch2: must be in (this patch is queued by Paul)
-patch3: will be taken care of by Paul's pwrdm fixes (I guess this is
queued by Paul himself already)
-patch4: OMAP interrupt count must be increased (this is handled by
Benoit's patch, which is queued by Tony)
-Tero
If not, I can queue this when Paul is ready to merge the IO wakeup
stuff.
