I have updated v4 to use the existing composite DTB build pattern: shikra-iqs-evk-m2-wifi-bt-dtbs := \         shikra-iqs-evk.dtb \         shikra-iqs-evk-m2-wifi-bt.dtbo dtb-$(CONFIG_ARCH_QCOM) += shikra-iqs-evk-m2-wifi-bt.dtb dtb-$(CONFIG_ARCH_QCOM) += shikra-iqs-evk-m2-wifi-bt.dtbo The composite DTB target makes Kbuild apply the overlay to shikra-iqs-evk.dtb and validates the symbols and fixups during the build. The standalone DTBO is retained because the existing FIT flow loads the base DTB and overlay separately. I am rerunning the kernel build with this change before sending v4. I will also reply to the individual Sashiko findings rather than leaving the automated reports unanswered On 10/22/2026 1:18 AM, Rob Herring wrote: > On Mon, Oct 19, 2026 at 9:09 PM Linghui Wu wrote: >> Add an overlay for M.2 Key-E Wi-Fi and Bluetooth modules on the Qualcomm >> Shikra IQS EVK. >> >> The M.2 variant uses the external module connected through the Key-E >> connector instead of the onboard WCN3988 devices.
