Subject: [PATCH 1/5] arm64: dts: qcom: sc7180: Add interconnect bindings for GPU
Date: Tue, 31 Mar 2020 13:25:49 +0530 [thread overview]
Message-ID: <1585641353-23229-2-git-send-email-smasetty@codeaurora.org> (raw)
In-Reply-To: <1585641353-23229-1-git-send-email-smasetty@codeaurora.org>
This patch adds the interconnect bindings to the GPU node. This enables
the GPU->DDR path bandwidth voting.
