Since this was spun off the original series I figured it would be best 
to treat it as v1 of a new series. It's unchanged since 
https://lore.kernel.org/lkml/20240112163608.528453-6-krzysztof.kozlowski@linaro.org/ 
so technically this is '[PATCH resend v3]'. I did rebase it on top of 
linux-next just to make sure it still worked.

Oops my bad. I think because by the time v3 rolled round it was part of 
your series I never added the Ack from Peter or your R-by to my local 
commit which is what I sent out. I've added it now if I send a v4 (or is 
it v2 of this?) I'll include the tags.
