The major difference between these two gem object is that drm_gem_cma_object is for CMA buffer and mtk_drm_gem_obj is for iommu buffer. This series just add two iommu feature which is used by mediatek drm driver into cma helper, so there is still some feature just support CMA buffer. The first feature is making sub device as dma device for dma operation. So far drm core treat drm device as dma device, but mediatek drm device is not a dma device and it use sub device as dma device. The second feature is providing interface to create dumb buffer without mapping kernel virtual address. For iommu buffer, mapping kernel virtual address would reduce free virtual memory area. Some feature still support only CMA buffer, for example, drm_gem_cma_prime_vmap(), so we still treat these helper function as 'cma' helper function.
