interconnect: qcom: Add OSM L3 interconnect provider support

2020-03-03T17:02:52+00:00

On some Qualcomm SoCs, Operating State Manager (OSM) controls the
resources of scaling L3 caches. Add a driver to handle bandwidth
requests to OSM L3 from CPU on SDM845 SoCs.

interconnect: qcom: Allow icc node to be used across icc providers

2020-03-03T17:02:52+00:00

Move the icc node ids to a common header, this will allow for
referencing/linking of icc nodes to multiple icc providers on
SDM845 SoCs.

interconnect: qcom: Add SC7180 interconnect provider driver

2020-03-03T17:02:52+00:00

Add driver for the Qualcomm interconnect buses found in SC7180 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.

interconnect: qcom: sdm845: Split qnodes into their respective NoCs

2020-02-28T10:11:40+00:00

In order to better represent the hardware and its different Network-On-Chip
devices, split the sdm845 provider driver into NoC specific providers.
Remove duplicate functionality already provided by the icc rpmh and
bcm voter drivers to calculate and commit bandwidth requests to hardware.

interconnect: qcom: Consolidate interconnect RPMh support

2020-02-28T10:11:40+00:00

Add bcm voter driver and add support for RPMh specific interconnect
providers which implements the set and aggregate functionalities that
translates bandwidth requests into RPMh messages. These modules provide
a common set of functionalities for all Qualcomm RPMh based interconnect
providers and should help reduce code duplication when adding new
providers.

interconnect: qcom: Use the standard aggregate function

2019-12-16T07:25:24+00:00

Now we have a common function for standard aggregation, so let's use it,
instead of duplicating the code.
