I'm working on 5250 based Spring Chromebook and noticed that v3.17-rc1
got some more iommu support. With the new CONFIG_DRM_EXYNOS_IOMMU=y my
machine stops booting. So I'm wondering, is any of this a fix for 3.17,
or is all of this "unrelated" -next material? Also, are you or someone
working on the respective DT changes for Exynos5?

Regards,
Andreas
