2023-01-18interconnect: qcom: sm8150: Drop IP0 interconnectsDmitry Baryshkov
Similar to the sdx55 and sc7180, let's drop the MASTER_IPA_CORE and SLAVE_IPA_CORE interconnects for this platform. There are no actual users of this interconnect. The IP0 resource will be handled by clk-rpmh driver.

2021-11-30interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregateMike Tipton
We're only adding BCMs to the commit list in aggregate(), but there are cases where pre_aggregate() is called without subsequently calling aggregate(). In particular, in icc_sync_state() when a node with initial BW has zero requests. Since BCMs aren't added to the commit list in these cases, we don't actually send the zero BW request to HW. So the resources remain on unnecessarily. Add BCMs to the commit list in pre_aggregate() instead, which is always called even when there are no requests.

The current probe/remove functions are implemented separately for each target, but they are almost identical. Replace them with common functions that can be used across all rpmh targets.

2020-10-27interconnect: qcom: use icc_sync state for sm8[12]50Dmitry Baryshkov
In addition to the rest of Qcom interconnect drivers use icc_sync_state for SM8150/SM8250 interconnect drivers to notify the interconnect framework when all consumers are probed and there is no need to keep the bandwidth set to maximum anymore. Also move the BCM initialization before creating the nodes to set the max bandwidth in hardware for the initialization/probing stage.

2020-09-08interconnect: qcom: Add SM8150 interconnect provider driverJonathan Marek
Add driver for the Qualcomm interconnect buses found in SM8150 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. Based on SC7180 driver and generated from downstream dts.
