[0/6] drm: zynqmp_dp: Misc. patches and debugfs support

Message

This series adds debugfs support for the zynqmp_dp driver. The intent is
to enable compliance testing or to help debug signal-integrity issues.

The first three patches are general improvements (and could be applied
independently), while the last three add debugfs support.


Sean Anderson (6):
  drm: zynqmp_dp: Downgrade log level for aux retries message
  drm: zynqmp_dp: Adjust training values per-lane
  drm: zynqmp_dp: Add locking
  drm: zynqmp_dp: Split off several helper functions
  drm: zynqmp_dp: Optionally ignore DPCD errors
  drm: zynqmp_dp: Add debugfs interface for compliance testing
