[PATCH v2 2/6] ARM: tegra: Add the fuse clock to the Tegra124 GPU
From: Sasha Levin
Date: Fri Oct 16 2026 - 12:41:08 EST
The GPU needs the fuse clock running while it is powered: the GM20B
on Tegra210 often fails to initialize without it, and the GK20A on
Tegra124 is expected to have the same requirement. Describe the fuse
clock so that the GPU driver can keep it enabled.
