Currently the interconnect framework provides the xlate() callback for mapping the endpoints from phandle arguments in DT. This is implemented by the provider drivers. But the endpoints (or the path between the endpoints) might have an additional attributes, which should be parsed and populated. During previous discussions [1], it was suggested that adding more and more DT properties will not scale very well. So instead of adding DT properties, such data should be put into the 'interconnects' arguments. This patchset is introducing a new xlate_extended() callback, which would allow the interconnect provider drivers to parse additional data (such as path tags) and allow the framework to make use of them. Thanks to Sibi for the preliminary feedback and testing this patchset on the sc7180 platform. The patchset is based on linux-next (next-20200723).
