[PATCH v6 10/11] dt-bindings: connector: pcie-m2-e: Add vendor LGA connector compatible

From: Loic Poulain <loic.poulain@oss.qualcomm.com>
Date: 2026-09-04 15:42:45
Also in: linux-arm-msm, linux-devicetree, linux-pci, linux-pm, lkml
Subsystem: open firmware and flattened device tree bindings, pcie m.2 power sequencing, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Manivannan Sadhasivam, Linus Torvalds

Some modules (e.g. the Qualcomm QCA2066/QCNFA765) expose the same M.2
Key E interface signals but are physically soldered as an LGA package
rather than plugged into a real M.2 Key E connector socket. Such designs
are not actual M.2 Key E connectors, so describe them with a dedicated
vendor-specific compatible while keeping "pcie-m2-e-connector" as a
fallback for the shared signal semantics.

Add "qcom,pcie-m2-1418-lga-connector" for the M.2 LGA 1418 found on
Arduino Ventuno Q (Monaco Monza).

Add "qcom,pcie-m2-1620-lga-connector" for the M.2 LGA 1620 found on
The Lenovo Thinkpad T14s.
