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'?

drm/etnaviv: submit support for in-fences Loosely based on commit f0a42bb5423a ("drm/msm: submit support for in-fences"). Unfortunately, struct drm_etnaviv_gem_submit doesn't have a flags field yet, so we have to extend the structure and trust that drm_ioctl will clear the flags for us if an older userspace only submits part of the struct.

drm/etnaviv: select CMA and DMA_CMA if available While this is no build dependency, etnaviv will only work correctly on most systems if CMA and DMA_CMA are enabled.

drm/etnaviv: hook up DRM GPU scheduler This hooks in the DRM GPU scheduler. No improvement yet, as all the dependency handling is still done in etnaviv_gem_submit. This just replaces the actual GPU submit by passing through the scheduler. Allows to get rid of the retire worker, as this is now driven by the scheduler.
