Subject: [PATCH 1/3] dt-bindings: gpu: nvidia,gk20a: Allow a fuse clock after the reference clock
Date: Tue, 13 Oct 2026 10:52:08 -0400 [thread overview]
Message-ID: <20261013145210.103565-1-sashal@kernel.org> (raw)
GM20B needs both its reference clock and the fuse clock while it is
powered, so allow "fuse" as a fourth clock after "ref".
Assisted-by: LLM
Signed-off-by: Sasha Levin <sashal@kernel.org>
