Add driver for the Qualcomm interconnect buses found in SM4450 based
platforms. The topology consists of several NoCs that are controlled
by a remote processor that collects the aggregated bandwidth for each

Please drop the _DISP paths, upstream will handle these with icc
tags.
sure, will handle this.

Nit, but please:

- make these one line, like this:
{ .compatible = "qcom,sm4450-aggre1-noc", .data = &sm4450_aggre1_noc },

- add the missing space before '}'
sure, will handle this.
