I will take the patches Mark ACKed and send them for v5.2 as
early as it gets in v5.1-rc* cycle.

For this one maybe you can post the changes on top and see what's
the best way forward ?

I agree that duplicating idle state parsing code across back-ends
is silly - we just want to keep PSCI and kernel data structure
decoupled.

Post the code on top and we will find a way forward, OK ?

Thanks,
