Hi Dave
     Do you mean that I need send you a branch, based on drm-next, merge with
iommu tree and rockchip drm?

Yes, grab drm-next, git pull the arm/rockchip branch from Joerg's
tree, put rockchip drm
patches on top, send me pull request.

I'll validate it then.

Dave.

Hi Dave
    I have send a pull request to you, with Joerg's iommu arm/rockchip branch.

    I got a same problem when use "make multi_v7_defconfig" as Heiko said:
        drivers/video/fbdev/Kconfig:5:error: recursive dependency detected!
        drivers/video/fbdev/Kconfig:5:    symbol FB is selected by DRM_KMS_FB_HELPER

        drivers/video/fbdev/Kconfig:374:    symbol FB_CYBER2000_DDC depends on FB_CYBER2000
        drivers/video/fbdev/Kconfig:362:    symbol FB_CYBER2000 depends on FB

    I was confused how to solve the recursive dependency, remove depends on ARM_DMA_USE_IOMMU & IOMMU_API?
