Subject: [PATCH v2 0/8] drm: zynqmp_dp: Misc. patches and debugfs support

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

Changes in v2:
- Fix kerneldoc
- Rearrange zynqmp_dp for better padding
- Document hpd_irq_work
- Split off the HPD IRQ work into another commit
- Expand the commit message
- Document debugfs files
- Add ignore_aux_errors and ignore_hpd debugfs files to replace earlier
  implicit functionality
- Attempt to fix unreproducable, spurious build warning
- Drop "Optionally ignore DPCD errors" in favor of a debugfs file
  directly affecting zynqmp_dp_aux_transfer.

Sean Anderson (8):
  drm: xlnx: Fix kerneldoc
  drm: zynqmp_dp: Downgrade log level for aux retries message
  drm: zynqmp_dp: Adjust training values per-lane
  drm: zynqmp_dp: Rearrange zynqmp_dp for better padding
  drm: zynqmp_dp: Don't retrain the link in our IRQ
  drm: zynqmp_dp: Add locking
  drm: zynqmp_dp: Split off several helper functions
  drm: zynqmp_dp: Add debugfs interface for compliance testing
