I will move the port/endpoint anchors to monaco.dtsi in v2. After testing v2 on qcs8300-ride-sx, BT init broke. qcs8300-ride-sx has a soldered WCN6855 and no M.2 Key E connector, but the pending series [1] uses of_graph_is_present() to detect whether an M.2 connector is present. Since of_graph_is_present() only checks for a 'port' child node, the empty anchors in monaco.dtsi caused hci_qca to incorrectly enter the M.2 pwrseq path on all monaco boards. v3 moves the port/endpoint nodes back to monaco-evk.dts. Please review. [1] https://lore.kernel.org/all/20260720-monza-wireless-v5-1-69ec6743543c@oss.qualcomm.com/ -- Best Regards, Wei Deng
