Apparently using a "pciVVVV,DDDD" compatible is one way, see bindings/net/wireless/qca,ath9k.yaml There's apparently exactly one example of this in in-tree devicetrees: boot/dts/rockchip/rk3399-gru-chromebook.dtsi I guess this is the way to go then, unless Rob has a different idea :) -- Hector Martin (marcan@xxxxxxxxx) Public Key: https://mrcn.st/pub
