Subject: [PATCH v2 0/3] drm/msm: Add display snapshot debugfs

From: Rob Clark <robdclark@...omium.org>

This series adds a "kms" debugfs file to dump display register + atomic
state, which is useful for debugging issues that don't trigger a display
error irq (such as dsi phy misconfiguration).

Rob Clark (3):
  drm/msm/disp: Tweak display snapshot to match gpu snapshot
  drm/msm/disp: Export helper for capturing snapshot
  drm/msm/debugfs: Add display/kms state snapshot
