From 26daa18e35ebc4e192ff55d021f1cd7e69d55487 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Wed, 21 May 2025 15:38:10 +0200 Subject: [PATCH] dt-bindings: PCI: qcom,pcie-sc8180x: Drop unrelated clocks from PCIe hosts 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.
