Subject: [PATCH v2 4/6] arm64: tegra: Add the fuse clock to the Tegra186 GPU
Date: Fri, 16 Oct 2026 12:06:57 -0400 [thread overview]
Message-ID: <20261016160700.3831336-5-sashal@kernel.org> (raw)
In-Reply-To: <20261016160700.3831336-1-sashal@kernel.org>
The GPU needs the fuse clock running while it is powered: Tegra194
already describes it for its GV11B, and the GM20B on Tegra210 often
fails to initialize without it, so the GP10B on Tegra186 is expected
to need it as well. Describe the fuse clock so that the GPU driver
can keep it enabled.
