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.

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.

2024-01-31interconnect: qcom: Add MSM8909 interconnect provider driverAdam Skladowski
Add driver for interconnect busses found in MSM8909 based platforms. The topology consists of three NoCs that are partially controlled by a RPM processor. In the downstream/vendor kernel from Qualcomm there is an additional "mm-snoc". However, it actually ends up using the same RPM "snoc_clk" as the normal "snoc". It looks like this is actually the same NoC in hardware and the "mm-snoc" was only defined to assign a different "qcom,util-fact" to increase bandwidth requests by a static margin. In mainline we can represent this by assigning the equivalent "ab_coeff" to all the nodes that are part of "mm-snoc" downstream.
