Instead of using the dma_buf functionality for GEM CMA, we can use prime
helpers if we can provide low-level hook functions for GEM CMA.Signed-off-by: Joonyoung Shim

Add helper to display fb's which can be used directly in drm_info_list:
static struct drm_info_list foo_debugfs_list[] = {
...
{ "fb", drm_fb_cma_debugfs_show, 0 },
};to display information about CMA fb objects, as well as a
drm_gem_cma_describe() which can be used if the driver bothers to keep
a list of CMA GEM objects.Signed-off-by: Rob Clark

Many embedded drm devices do not have a IOMMU and no dedicated
memory for graphics. These devices use CMA (Contiguous Memory
Allocator) backed graphics memory. This patch provides helper
functions to be able to share the code. The code technically does
not depend on CMA as the backend allocator, the name has been chosen
because CMA makes for a nice, short but still descriptive function
prefix.Signed-off-by: Sascha Hauer
