Subject: [PATCH v2 1/3] dt-bindings: arm: qcom,coresight-static-replicator: Add property for source filtering
The is some "magic" hard coded filtering in the replicators,
which only passes through trace from a particular "source". Add
a new property "filter-src" to label a phandle to the coresight
trace source device matching the hard coded filtering for the port.
