Hi,

Usually the TI SN65DSI83 recovers from error by itself but during ESD
tests, we have some cases where the TI SN65DSI83 didn't recover.

In order to handle those cases, this series adds support for a recovery
mechanism.

Compare to the previous iteration, this v2 series mainly:
  - Rebase patches on top of v6.13-rc3.
  - Reset the output path where the bridge is located instead of the
    full pipeline.
  - Add more information in a commit log.

Best regards,
Hervé Codina
