There were several properties added within last months, so in total you
changed these bindings quite a lot. Please convert them to YAML.

If there is only one, then I think it's perfectly fine that we postpone
the introduction of an array and the loops etc.

But if you see a reason to support multiple paths, I think we should
utilize the icc bulk API.

devm_of_icc_get() will return an "enabled" path, but from that point we
can use icc_enable() and icc_disable() to toggle if our vote should be
taking part in the aggregation.

By using that we should be able to just icc_set_bw() in
q6v5_interconnect_init(), call icc_disable() and from there on we can
wrap our proxy vote in icc_enable() and icc_disable(). That way you
don't need to copy average_bandwidth and peak_bandwidth into the
interconnect_info.

Bjorn

Looked at this again, and it makes me wonder why do we need to vote on
the path LLCC -> EBI1 and why do we call that path "imem"?
