Hm, one thing we're missing here still I think is that right now there's
not yet a BAT for psr. At least I didn't spot anything in the CI overview.
Is there a super-basic PSR testcase (just checking that we go into psr
self-refresh is imo good enough), similar to what we have with runtime PM?
Also I guess we need to get the dp aux series from you in first. With BAT
and outstanding series merged:
