The "wakeup-interrupt" property at the bridge level basically has to be defined as the wakeup interrupt for all devices on the bus under the bridge.The only thing I'm at a loss for is whether this goes in (referring to rk3399-gru.dtsi) &pcie or &pci_rootport. I think some versions of this series have been aiming for the former, and some the latter.I'd keep the wakeup interrupt property at the rootport level. That way it can work with whatever pcie card that might be plugged into that slot. That is in case it's just a slot and not hardwired pcie device :)
Do I understand correctly that &pcie is the device and the &pci_rootport is the port that device is connected to?
