[PATCH] drm/vc4: Initialize vc4_drm_driver with CMA helper defaults
by Thomas Zimmermann 14 Jan '21

14 Jan '21

The function vc4_prime_import_sg_table() is an otherwise empty wrapper around CMA's drm_gem_cma_prime_import_sg_table(). Removing it in favor of the latter allows to initialize vc4_drm_driver with CMA's initializer macro.

Similar to a9d9fea74be2 ("drm/mediatek: mtk_dsi: Create connector for bridges"): Use the drm_bridge_connector helper to create a connector for pipelines that use drm_bridge. This allows splitting connector operations across multiple bridges when necessary, instead of having the last bridge in the chain creating the connector and handling all connector operations internally.
