      drm/nouveau: Clean up nv50_head_atomic_check_mode() and fix blankus calculation · 35dd9874
      Alastair Bridgewater authored
      drm_mode_set_crtcinfo() does compensation for interlace and
      doublescan timing effects already, so do it first and use the
      compensated figures instead of the constant "vscan / ilace" terms
      that we had before.
      
      And then it turns out that the hardware model for how the timing
      parameters are configured is basically the standard model, but
      starting one clock before the sync pulse rather than at the start
      of the display area, which lets us drastically simplify the
      overall timing calculations (verifying the changes by algebraic
      operations is left as an exercise for the reader).
      
      Finally, there were a couple of issues with the computation of
      m->v.blankus that are addressed here.  Interlaced modes would
      generate a negative intermediate result.  Double scan modes would
      generate an overestimate rather than an underestimate.  And when
      enabling frame-packing modes, a rather extreme overestimate would
      be generated.  Fixed, by using the timings as adjusted for the
      CRTC to find the length of the vertical blanking period instead of
      mixing adjusted and pre-adjustment timing parameters.

      imx-drm: cleanups and YUV 4:2:0 memory read/write reduction support
      
      - Remove counter load enable form PRE, which has no effect.
      - Add support for setting the double read/write reduction flag in channel
        parameter memory. This can be used to save some memory bandwidth when
        capturing in YUV 4:2:0 chroma subsampled formats.
      - Allocate DMA channel structures as needed, most of the 64 channels are
        unused or even reserved.
      - Remove unused interrupt busy waiting routine.
      - Set VDIC field order for both AUTO and MAN inputs simultaneously as
        both can't be active at the same time.

      Dave Airlie authored
      The series interleaves DRM and V4L2 patches due to dependencies between the R-
      Car DU and VSP drivers. Mauro has acked all the V4L2 patches to go through
      your tree, and they don't conflict with anything queued for v4.13 in his tree.
      If I need to send any conflicting patches through Mauro's tree for v4.13, I'll
      make sure to base them on this branch.

      sun4i-drm changes for 4.13
      
      An unusually big pull request for this merge window, with three notable
      features:
        - V3s display engine support. This is especially notable because it uses
          a different display engine used on the newer Allwinner SoCs (H3, A64
          and the likes) that will be quite easily supported now.
        - HDMI support for the old Allwinner SoCs. This is enabled only on the
          A10s for now, but should be really easy to extend to deal with A10, A20
          and A31
        - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
          etc.). It currently ignores the second pipeline, but we can use the
          dual-pipelines bindings. This will be useful to enable the display
          pipeline while we work on the dual-pipeline.
