Do we need a Fixes tag for this? I would recommend to split imx_icc_get_bw and imx_icc_aggregate changes into separate patches. These also seem to be unrelated to the imx_icc_node_adj_desc patchset.

The aggregate function will return whatever is the highest rate for that specific node. The imx_icc_get_bw sets the initial avg and peak to 0 in order to avoid setting them to INT_MAX by the interconnect core.
