This looks like it's fixing a bug in commit d42fae738f3a ("arm64: dts: qcom: Add LTE SKUs for sc7280-villager family") which removed a fragment from "sc7280-chrome-common.dtsi" but then didn't add it back to all the previous users. Not sure how I missed that. In any case, feels like this should be a separate commit with a Fixes. ...also: instead of adding this include to crd-r3 and idp2, though, why not just add it to "idp.dtsi"? Right now all things that include "idp.dtsi" are LTE SKUs, right? > / { > model = "Qualcomm Technologies, Inc. sc7280 CRD platform (rev3 - 4)"; > diff --git a/arch/arm64/boot/dts/qcom/sc7280-herobrine-evoker-r0.dts b/arch/arm64/boot/dts/qcom/sc7280-herobrine-evoker-r0.dts > index ccbe50b6249a..6a2ffaac33bc 100644 > --- a/arch/arm64/boot/dts/qcom/sc7280-herobrine-evoker-r0.dts > +++ b/arch/arm64/boot/dts/qcom/sc7280-herobrine-evoker-r0.dts > @@ -8,6 +8,7 @@ > /dts-v1/; > > #include "sc7280-herobrine.dtsi" > +#include "sc7280-herobrine-wifi-sku.dtsi" I think this is wrong and evoker is a LTE SKU.

I think you need to move the existing "villager-r1.dts" to be a dtsi file and then include it from both the new "villager-r1.dts" and "villager-r1-lte.dts"
