Subject: [PATCH v6 5/6] arm64: dts: qcom: sc7180: Add interconnects property for GPU
Date: Fri, 17 Jul 2020 18:59:38 +0530 [thread overview]
Message-ID: <1594992579-20662-6-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1594992579-20662-1-git-send-email-akhilpo@codeaurora.org>
From: Sharat Masetty <smasetty@codeaurora.org>
This patch adds the interconnects property to the GPU node. This enables
the GPU->DDR path bandwidth voting.
