Subject: [PATCH 3/3] arm64: dts: mediatek: mt8188: Add the MFGCFG phandle to the GPU
Date: Sat, 3 Oct 2026 22:01:32 +0200 [thread overview]
Message-ID: <20261003200132.866240-4-michal@nozomi.space> (raw)
In-Reply-To: <20261003200132.866240-1-michal@nozomi.space>
The GPU driver needs the MFG configuration block to enable the GPU
timestamp counter, which otherwise reads zero.
