The kernel is built before without errors.

I got 2 warnings from the make kitakami_defconfig:

warning: (PCI_MSM && AMD_IOMMU) selects PCI_MSI which has [COLOR="red"]unmet direct dependencies (PCI && ARCH_SUPPORTS_MSI)[/COLOR]
warning: (ARCH_MSM) selects DEVFREQ_GOV_MSM_BW_HWMON which has [COLOR="red"]unmet direct dependencies (PM_DEVFREQ && (ARCH_MSM_KRAIT || ARCH_MSM_BIMC_BWMON))[/COLOR]

Should I bother? make runs fine...

I am on Debian testing. Python 2.7.10

looking into .apq8094-v2.1-kitakami_karin_windy.dtb.dts.tmp in directory 28.0.A.7.24/kernel/arch/arm/boot/dts/ I find e.g.

qcom,msm-id = <253 0x10000>;

.

It does not make it into apq8094-v1-kitakami_karin_windy.dtb

Any hints how I could proceed to the dt.img?
