Hi Andrew,

I think it's problematic to create a bind between the NPU and
PCIe.

Do you have any hint on how it's possible to read the PCI
device attached? I'm not aware of any API that can be used
to enumerate what pcie devices is present on the device?

Considering how tightly integrated things are in this SoC
I still feel firmware-names is the most effective solution
for this. The WiFi offload is mostly optional and sadly
due to Airoha limitation, it's not possible to have separate
blob for the single feature/support.
