This patch series brings some fixes to the Qualcomm DPU driver, aim is
to get it prepared for "legacy" SoCs (like MSM8998, SDM630/660) and to
finally get command-mode displays working on this driver.

The series was tested against MSM8998 (the commit that introduces it to
the hw-catalog is not included in this series, as it needs to be cleaned
up a little more) and specifically on:
- Sony Xperia XZ Premium (MSM8998), 4K dual-dsi LCD display, command-mode
- F(x)Tec Pro1 (MSM8998), single-dsi OLED display, video-mode

... And it obviously worked just perfect!

Changes in v2:
- Dropped patches "drm/msm/dpu: Add a function to retrieve the current CTL status"
  and "drm/msm/dpu: Fix timeout issues on command mode panels" as the
  second patch was wrong.
- Fixed patch apply issues on latest linux-next and 5.11-rcX

AngeloGioacchino Del Regno (7):
  drm/msm/dpu: Fix VBIF_XINL_QOS_LVL_REMAP_000 register offset
  drm/msm/dpu: Move DPU_SSPP_QOS_8LVL bit to SDM845 and SC7180 masks
  drm/msm/dpu: Add prog_fetch_lines_worst_case to INTF_BLK macro
  drm/msm/dpu: Allow specifying features and sblk in DSPP_BLK macro
  drm/msm/dpu: Disable autorefresh in command mode
  drm/msm/dpu: Correctly configure vsync tearcheck for command mode
  drm/msm/dpu: Remove unused call in wait_for_commit_done

Any updates on submitting hw catalog patches? If they are not yet fully 
ready, could you please send an RFC or DRAFT patch for the reference?
