Subject: [PATCH v2 5/6] arm64: tegra: Add the fuse clock to the Tegra210 GPU
Date: Fri, 16 Oct 2026 12:06:58 -0400 [thread overview]
Message-ID: <20261016160700.3831336-6-sashal@kernel.org> (raw)
In-Reply-To: <20261016160700.3831336-1-sashal@kernel.org>
The GM20B GPU on Tegra210 needs the fuse clock running while it is
powered. Describe it so that the GPU driver can keep it enabled.
Fixes: d1b725476104 ("arm64: tegra: p2180: Explicitly enable GPU")
Assisted-by: LLM
