I also noticed other boards using bcm4329-fmac in similar situations. https://patchwork.kernel.org/patch/9739181/ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/amlogic/meson-gxbb-nanopi-k2.dts?h=v4.13-rc7 I will resend "NanoPi NEO Plus2" dts with "brcm,bcm4329-fmac" and see where it goes. regards, -antony
