Subject: [PATCH v2 1/4] dt-bindings: display/msm: add core clock to the mdss bindings
Date: Mon, 9 Jan 2023 02:52:06 +0200 [thread overview]
Message-ID: <20230109005209.247356-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230109005209.247356-1-dmitry.baryshkov@linaro.org>
Add (optional) core clock to the mdss bindings to let the MDSS driver
access harware registers before MDP driver probes.
