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/gpu/drm/Kconfig:34: symbol DRM_KMS_FB_HELPER is selected by DRM_ROCKCHIP drivers/gpu/drm/rockchip/Kconfig:1: symbol DRM_ROCKCHIP depends on ARM_DMA_USE_IOMMU arch/arm/Kconfig:95: symbol ARM_DMA_USE_IOMMU is selected by VIDEO_OMAP3 drivers/media/platform/Kconfig:96: symbol VIDEO_OMAP3 depends on VIDEO_V4L2 drivers/media/v4l2-core/Kconfig:6: symbol VIDEO_V4L2 depends on I2C drivers/i2c/Kconfig:7: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:59: symbol FB_DDC is selected by FB_CYBER2000_DDC 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? - Mark
