    drm: mali-dp: Add writeback connector · 8cbc5caf
    Brian Starkey authored
    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
