Subject: [PATCH v4 1/4] dt-bindings: arm: coresight: Add new compatible for static replicator
Date: Sat,  6 Apr 2019 19:21:42 +0800	[thread overview]
Message-ID: <20190406112145.15184-2-leo.yan@linaro.org> (raw)
In-Reply-To: <20190406112145.15184-1-leo.yan@linaro.org>

CoreSight uses below bindings for replicator:

  Static replicator, aka. non-configurable replicator:
    "arm,coresight-replicator";

  Dynamic replicator, aka. configurable replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";

The compatible string "arm,coresight-replicator" is not an explicit
naming to express the replicator is 'static'.  To unify the naming
convention, this patch introduces a new compatible string
"arm,coresight-static-replicator" for the static replicator; the
compatible string "arm,coresight-replicator" is still kept thus we
can support the old DT binding, but tag it as obsolete and suggest
to use the new compatible string.

As result CoreSight replicator have below bindings:

  Static replicator:
    "arm,coresight-replicator"; (obsolete)
    "arm,coresight-static-replicator";

  Dynamic replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";
