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 Reviewed-by: Suzuki K Poulose Reviewed-by: Rob Herring Signed-off-by: Mathieu Poirier --- Documentation/devicetree/bindings/arm/coresight.txt | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/arm/coresight.txt b/Documentation/devicetree/bindings/arm/coresight.txt index f8aff65ab921..d02d160fa8ac 100644 --- a/Documentation/devicetree/bindings/arm/coresight.txt +++ b/Documentation/devicetree/bindings/arm/coresight.txt @@ -69,7 +69,10 @@ its hardware characteristcs. * compatible: Currently supported value is (note the absence of the AMBA markee): - - "arm,coresight-replicator" + - Coresight Non-configurable Replicator: + "arm,coresight-static-replicator"; + "arm,coresight-replicator"; (OBSOLETE.
