This is v3 of [1], addressing the review comments and adding R-bs from
Ville, the main changes being:
- Add the link check work to intel_encoder and the corresponding helper
functions to a new intel_encoder.c file. (Patch 7)
- Add documentation/asserts on intel_atomic_state being valid for MST
vs. possibly NULL for SST links in the link training functions.
(Patch 9,10)
- Lock connection_mutex in the debugfs entries only for the required
intel_dp state. (Patch 17-21)
- Remove the link training info debugfs entry showing the link retrain,
link training failure counters and the retrain disabled state, add a
separate debugfs entry showing only the retrain disabled state.
(Patch 21)
