The mxsfb driver uses the default implementation for CMA functions. The DRM_GEM_CMA_DRIVER_OPS macro now sets these defaults in struct drm_driver.
Using DRM_GEM_CMA_DRIVER_OPS introduces several changes: the driver now sets .gem_create_object to drm_cma_gem_create_object_default_funcs(), which sets CMA GEM object functions. GEM object functions implement the rsp operations where possible. Corresponding interfaces in struct drm_driver are cleared. Prime import now uses drm_gem_cma_prime_import_sg_table_vmap(), which maps the imported buffer upon import. Mmap operations are performed by drm_gem_prime_mmap(), which goes through GEM file operations. These changes have been part of the aspeed driver for some time.
