Rather than hooking up the PM domains through devm_pm_opp_attach_genpd()
and manage the device-link, let's avoid the boilerplate-code by converting
into dev_pm_domain_attach|detach_list.

Rather than hooking up the PM domains through _opp_attach_genpd() and
manually manage runtime PM for the corresponding virtual devices created by
genpd during attach, let's avoid the boilerplate-code by converting into
dev_pm_domain_attach|detach_list.

Please don't.

I should have stated that this depends on another series [1] - and
they need either to go together or we need to defer $subject patch
until the next release cycle.

Kind regards

Sure, then I guess we will deffer venus patch until the preparation 
series is merged to avoid conflicts. Thank you!

Assuming the preparation series gets accepted, maybe we can give it a
try via my pmdomain tree? Or do expect to land a lot of code that
could conflict?

I also realized that I already have a different series [1] queued in
my pmdomain tree from Dikshita Agarwal (reviewed by Bryan), that moves
an existing call for dev_pm_domain_attach() to the new
devm_pm_domain_attach() helper. So far I haven't received any reports
about conflicts from linux-next, so it looks good I think.

Kind regards
Uffe

Please take it via pmdomain tree. Thank you!
