Subject: [PATCH 6/6] arm64: dts: mediatek: mt8173: Add GPU device nodes
Date: Thu, 30 May 2024 16:35:05 +0800
Message-ID: <20240530083513.4135052-7-wenst@chromium.org>

The MediaTek MT8173 comes with a PowerVR Rogue GX6250, which is part
of the Series6XT, another variation of the Rogue family of GPUs.

On top of the GPU is a glue layer that handles some clock and power
signals.

Add device nodes for both.
