Subject: [PATCH 4/4] arm64: dts: qcom: sm8150: Drop unrelated clocks from PCIe hosts
Date: Wed, 21 May 2025 15:38:13 +0200	[thread overview]
Message-ID: <20250521-topic-8150_pcie_drop_clocks-v1-4-3d42e84f6453@oss.qualcomm.com> (raw)
In-Reply-To: <20250521-topic-8150_pcie_drop_clocks-v1-0-3d42e84f6453@oss.qualcomm.com>

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

The TBU clock belongs to the Translation Buffer Unit, part of the SMMU.
The ref clock is already being driven upstream through some of the
branches.
