Hi Sean,

This series cleans up the zyqnmp_dp IRQ and locking situation. Once
that's done, it adds debugfs support. The intent is to enable compliance
testing or to help debug signal-integrity issues.

Last time I discussed converting the HPD work(s) to a threaded IRQ. I
did not end up doing that for this series since the steps would be

- Add locking
- Move link retraining to a work function
- Harden the IRQ
- Merge the works into a threaded IRQ (omitted)

Which with the exception of the final step is the same as leaving those
works as-is. Conversion to a threaded IRQ can be done as a follow-up.

What is the base for this series? I'm having trouble applying it.

I managed to mostly apply it, but I see the board hang when I unload the modules. I didn't debug it as it might as well be caused by my conflict resolution.

The base is v6.8-rc1, but it should probably be v6.9. I can rebase and resend.

Did you have something extra in your branch before the series? I got "error: sha1 information is lacking or useless".
