	  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.
DRM: Armada: Add Armada DRM driver This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.

drm: add more MMU dependencies 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'?
