Subject: [RFC PATCH 1/3] dt-bindings: display/msm/gpu: allow specifying MX domain A5xx
Date: Thu, 30 Mar 2023 01:24:58 +0300 [thread overview]
Message-ID: <20230329222500.1131836-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230329222500.1131836-1-dmitry.baryshkov@linaro.org>
Some a5xx Adreno devices might need additional power domains to handle
voltage scaling. While we do not (yet) have support for CPR3 providing
voltage scaling, allow specifying MX domain to scale the memory cell
voltage.
