Some Qualcomm platforms require to power up an external device before probing the PCI bus. E.g. on RB5 platform the QCA6390 WiFi/BT chip needs to be powered up before PCIe0 bus is probed. Add a quirk to the respective PCIe root bridge to attach to the power domain if one is required, so that the QC
