Many DRM drivers only work with an MMU, and after the patch to enable core DRM support without MMU, we already had one fixup for many of them. The etnaviv, armada and msm drivers were missed and have the same problem: warning: (DRM_ETNAVIV) selects IOMMU_SUPPORT which has unmet direct dependencies (MMU) warning: (DRM_I915 && DRM_MSM && DRM_ETNAVIV) selects SHMEM which has unmet direct dependencies (MMU) drivers/gpu/drm/armada/armada_gem.o: In function `armada_gem_vm_fault': armada_gem.c:(.text.armada_gem_vm_fault+0x14): undefined reference to `vm_insert_pfn' arch/arm/mm/dma-mapping.c: In function '__iommu_alloc_remap': arch/arm/mm/dma-mapping.c:1390:4: error: 'VM_ARM_DMA_CONSISTENT' undeclared (first use in this function) arch/arm/mm/dma-mapping.c:1456:31: error: 'atomic_pool' undeclared (first use in this function); did you mean 'atomic_xor'?

Support the "LCD" controllers found on the Marvell Armada 510
|
|
devices. There are two controllers on the device, each controller
|
|
supports graphics and video overlays.
|

|
|
This driver provides no built-in acceleration; acceleration is
|
|
performed by other IP found on the SoC. This driver provides
|
|
kernel mode setting and buffer management to userspace.
