It depends on the "Fixes/improvements for the PCI M.2 power sequencing driver" series (V3): https://lore.kernel.org/r/20260519-pwrseq-m2-bt-v3-0-b39dc2ae3966@oss.qualcomm.com Patch 1 adds 0x1103 (WCN6855) to pwrseq_m2_pci_ids[] alongside the existing 0x1107 (WCN7850) entry, with compatible "qcom,wcn6855-bt". Patch 2 describes the M.2 Key E connector on lemans-evk: - pcie-m2-e-connector node, port@0 -> pcieport0, port@3 -> uart17 (BT serdev path) - vreg_dcin_12v (12V) + vreg_wcn_3p3 (3.3V, vin-supply 12V), both always-on/boot-on, as required by the binding - compatible = "pciclass,0604" on pcieport0 in lemans.dtsi so the PCI subsystem can match the DT node to the PCI-to-PCI bridge - serial1 = &uart17 alias Wei Deng (2): power: sequencing: pcie-m2: Add PCI ID 0x1103 for WCN6855 Bluetooth arm64: dts: qcom: lemans-evk: Describe the PCIe M.2 Key E connector arch/arm64/boot/dts/qcom/lemans-evk.dts | 75 +++++++++++++++++++++++ arch/arm64/boot/dts/qcom/lemans.dtsi | 1 + drivers/power/sequencing/pwrseq-pcie-m2.c | 2 + 3 files changed, 78 insertions(+) -- 2.34.1
