On Spring, I am able to boot my kgene/for-next based queue with just:

mfd: syscon: Decouple syscon interface from platform devices
arm: dts: Exynos5: Use pmu_system_controller phandle for dp phy

with DRM_EXYNOS*=y (except IOMMU) and SND_SOC_SNOW=m enabled in the
config, while using simplefb rather than the Exynos DRM and thus
clk_ignore_unused.

Regarding SND_SOC_SNOW: Note that I recently submitted a patch to enable
module-loading, which is missing in kgene/for-next and -rc5 but is in
linux-next.git - it might uncover problems that previously went
unnoticed: https://patchwork.kernel.org/patch/5235951/
exynos_defconfig has SND_SOC_SNOW=y, whereas multi_v7_defconfig doesn't
have it.

Regards,
Andreas
