interconnect: qcom: icc-rpmh: Consolidate probe functions

2021-07-22T07:05:24+00:00

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.

interconnect: qcom: sc7180: Init BCMs before creating the nodes

2020-10-15T06:24:00+00:00

Currently if we use sync_state, by default the bandwidth is maxed out,
but in order to set this in hardware, the BCMs (Bus Clock Managers) need
to be initialized first. Move the BCM initialization before creating the
nodes to fix this.

interconnect: qcom: Use icc_sync_state

2020-09-18T05:57:18+00:00

Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Now by
default the framework sets the bandwidth to maximum during boot. We need
to use the icc_sync_state callback to notify the framework when all
consumers are probed and there is no need to keep the bandwidth set to
maximum anymore.

interconnect: qcom: sc7180: Replace xlate with xlate_extended

2020-09-08T13:29:01+00:00

Use the qcom_icc_xlate_extended() in order to parse tags, that are
specified as an additional arguments to the path endpoints in DT.

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.
