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.
