Mali-DP has a memory writeback engine which can be used to write the composition result to a memory buffer. Expose this functionality as a DRM writeback connector on supported hardware. Changes since v1: Daniel Vetter: - Don't require a modeset when writeback routing changes - Make writeback connector always disconnected Changes since v2: - Rebase onto new drm_writeback_connector - Add reset callback, allocating subclassed state Daniel Vetter: - Squash out-fence support into this commit Gustavo Padovan: - Don't signal fence directly from driver (and drop malidp_mw_job) Changes since v3: - Modifications to fit with Mali-DP commit tail changes Signed-off-by: Brian Starkey <brian.starkey@arm.com> [rebased and fixed conflicts] Signed-off-by: Mihail Atanassov <mihail.atanassov@arm.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com>
