      drm: rcar-du: Clarify error message when encoder initialization fails · 64549cdf
      Laurent Pinchart authored
      A failure to initialize an encoder currently prints an error message in
      the kernel log without mentioning which encoder failed to initialize. To
      help debugging initialization issues print the encoder DT node name.
      
      This requires moving the error message to the rcar_du_encoders_init_one
      function and refactoring it slightly.

      drm: rcar-du: Fix crash with groups that have less than 9 planes · d6aed574
      Laurent Pinchart authored
      Commit 917de180 ("drm: rcar-du: Implement universal plane support")
      made the number of planes per group dynamic, but didn't update all loops
      over the planes array, resulting in out-of-bound accesses on DU
      instances that have an odd number of CRTCs (such as the R8A7790). Fix
      it.

      drm: rcar-du: Disable all planes when stopping the CRTC · 911316fe
      Laurent Pinchart authored
      The DSnPR plane configuration registers are updated on vblank, and no
      vblank will occur once the CRTC is stopped. We thus can't only disable
      planes right before starting the CRTC as it would start scanning out
      immediately from old frame buffers until the next vblank.
      
      Fix the problem by disabling all planes when stopping the CRTC and wait
      for the change to take effect. This increases the CRTC stop delay,
      especially when multiple CRTCs are stopped in one operation as we now
      wait for one vblank per CRTC. Whether this can be improved needs to be
      researched.

      Atomic modesetting support for omapdrm.
      
      " we've had issues with omapdrm for years,
      which we've not been able to fix properly (like warnings/crashes when unloading
      modules, page-flips tearing, race issues with fbs). All those problems seem to
      be gone after this rewrite of omapdrm for atomic modesetting, and the resulting
      code is much cleaner and more maintainable."
