interconnect: qcom: sm8550: Remove bogus per-RSC BCMs and nodes

2024-01-31T13:47:47Z

The downstream kernel has infrastructure for passing votes from different interconnect nodes onto different RPMh RSCs. This neither implemented, not is going to be implemented upstream (in favor of a different solution using ICC tags through the same node). Unfortunately, as it happens, meaningless (in the upstream context) parts of the vendor driver were copied, ending up causing havoc - since all "per-RSC" (in quotes because they all point to the main APPS one) BCMs defined within the driver overwrite the value in RPMh on every aggregation. To both avoid keeping bogus code around and possibly introducing impossible-to-track-down bugs (busses shutting down for no reason), get rid of the duplicated BCMs and their associated ICC nodes.

interconnect: qcom: Add SM8550 interconnect provider driver

2022-12-29T09:36:33Z

Add driver for the Qualcomm interconnect buses found in SM8550 based platforms. The topology consists of several NoCs that are controlled by a remote processor that collects the aggregated bandwidth for each master-slave pairs.
