Thanks for the link. Sorry I still don't get the complete picture. Who are
the consumers of these clock nodes if not cpufreq itself.

I am going to guess, so other device(like inter-connect) with phandle into
CPU device perhaps ? Also I assume it will have phandle to non-CPU device
and hence we need generic device clock solution. Sorry for the noise, but
I still find having both clocks and qcom,freq-domain property is quite
confusing but I am fine as I understand it bit better now.
