I was going to do patch 4 > too, but it doesn't apply. Thanks, I have tried to applied on drm-misc/for-linux-next but it doesn't apply too. It looks like commit d5ff1adb3809e2f74a3b57cea2e57c8e37d693c4 is missing on drm-misc ? https://github.com/torvalds/linux/commit/d5ff1adb3809e2f74a3b57cea2e57c8e37d693c4#diff-c3172f5d421d492ff91d7bb44dd44917 Clément > > Patch 2 can go in via the iommu tree and the rest via the allwinner tree. > > Rob
