Hi all,

This series from Aapo adds support for USB4 v2 Gen 4 link symmetric and
asymmetric receiver lane margining. Useful for instance on manufacturing
floor to check stability of the electrical signaling.

Aapo Vienamo (8):
  thunderbolt: Don't hardcode margining capabilities size
  thunderbolt: debugfs: Add USB4 Gen 4 margining capabilities
  thunderbolt: debugfs: Implement Gen 4 margining eye selection
  thunderbolt: debugfs: Replace "both lanes" with "all lanes"
  thunderbolt: debugfs: Replace margining lane numbers with an enum
