Subject: [PATCH 06/17] dt-bindings: arm: coresight: Add optional property to replicators
Date: Thu, 16 Jul 2020 11:57:35 -0600	[thread overview]
Message-ID: <20200716175746.3338735-7-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200716175746.3338735-1-mathieu.poirier@linaro.org>

From: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>

Add an optional boolean property "qcom,replicator-loses-context" to
identify replicators which loses context when AMBA clocks are removed
in certain configurable replicator designs.
