The rcar-du driver uses the default implementation for CMA functions; except
for the .dumb_create callback. The DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE()
macro now sets these defaults and .dumb_create in struct drm_driver.
By using DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE() 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.
