I spent hours checking .dts files for the similar devices without success.
I have this card working in u7628 router (mt7628 based) without any tricks or modifications, here is the corresponding .dtsi
Another similar device seems to be WE1026-5G, it uses exactly the same 5GHz card. PCI configuration is in this .dtsi
I already have pciutils included:
