Hi Everyone,

These two patches complement the recently made PM core changes related to
the async suspend and resume of devices. They should apply on top of
6.16-rc3.

They were sent along with the other changes mentioned above:

https://lore.kernel.org/linux-pm/2651185.Lt9SDvczpP@xxxxxxxxxxxxx/

(and this is v4 because they have been rebased in the meantime), but they don't
make any difference on my test-bed x86 systems, so I'd appreciate a confirmation
that they are actually needed on ARM (or another architecture using DT).

Thanks!

Hi Rafael,

I haven't yet got the time to test these, but the code looks good to
me, so feel free to add for the series:

Kind regards

I passed this series to some internal guys to test on a wide variety of AMD x86 hardware. The initial testing looks good.
Will keep you apprised if anything pops up.
