Hi Sibi,

as I mentioned previously, in order not to add a needless stream of SCMI
Perf accessors I posted this:

https://lore.kernel.org/linux-arm-kernel/20240129151002.1215333-1-cristian.marussi@arm.com/T/#u

to expose all the Perf domains infos via the usual info_get(), similarly
to how other SCMI protocols do already.

I think that reworking this series on that, you can certainly drop this patch and just
check the _notify booleans on the retrieved domain info.

Thanks,
Cristian
