dt-bindings: arm: coresight: Add new compatible for static replicator
CoreSight uses below bindings for replicator: Dynamic replicator, aka. configurable replicator: "arm,coresight-dynamic-replicator", "arm,primecell"; Static replicator, aka. non-configurable replicator: "arm,coresight-replicator"; 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 kept for backward compatibility, but tag it as obsolete and suggest to use the new compatible string. As result CoreSight replicator have below bindings: Dynamic replicator: "arm,coresight-dynamic-replicator", "arm,primecell"; Static replicator: "arm,coresight-static-replicator"; "arm,coresight-replicator"; (obsolete) Signed-off-by: Leo Yan <leo.yan@linaro.org> Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
