Subject: [PATCH 2/2] dt-bindings: opp: Add binding for qcom-cpu-opp
Date: Wed, 1 Sep 2021 17:55:59 +0200 [thread overview]
Message-ID: <20210901155559.627491-2-angelogioacchino.delregno@somainline.org> (raw)
In-Reply-To: <20210901155559.627491-1-angelogioacchino.delregno@somainline.org>
This adds a binding documenting operating-points-v2-kryo-cpu in a
qcom-cpu-opp.yaml file. Logic is to add any new Qualcomm SoCs CPU
related OPP compatibles in here.
