Hi Conor, Krzysztof

I replied you both here.

i.MX95 use SCMI firmware, the SCP processor handles
clock/power/pinmux/reset/performance and etc.

I just add the index that SCMI exports, and Linux/UBoot
will use the index and go through SCMI to do real HW
configuration.

In such case, should I still add HW information in
a yaml binding doc? I am not sure what should be added
if yes.

Thanks,
Peng.
