I wish stable users of DT bindings (so some 3rd party projects or
product trees) keep testing their stable kernels, their stable DTS with
the bindings, whenever they upgrade their LTS kernel. And if they keep
testing then they should be told about lack of the power domain. That's
why this is for.

Of course fix impact is pretty small, so I don't mind if the stable tag
is being dropped here, but I will not resend just for that unless PCI or
stable maintainers ask me.

Best regards,
Krzysztof
