I believe they've been busy recently and haven't had time to revisit this work,
so I've rebased their patches to the latest upstream tree, incorporated the
review feedback I previously gave, and added a couple more fixes on top.

Kumar, Mahesh (5):
  drm/i915/skl+: Use plane size for relative data rate calculation
  drm/i915/skl+: calculate ddb minimum allocation (v3)
  drm/i915/skl+: calculate plane pixel rate (v3)
  drm/i915/skl+: Use scaling amount for plane data rate calculation (v3)
  drm/i915/skl: WA for watermark calculation based on Arbitrated Display
    BW (v4)

Matt Roper (2):
  drm/i915/gen9: Hold wm_mutex around SKL watermark updates
  dmi: Move memdev_dmi_entry definition to dmi.h

Shobhit Kumar (1):
  drm/i915: Add support to parse DMI table and get platform memory info
