Hello Mark, There are no routes in cs42l51_routes table using "Mic Bias" widget. I use this widget in a route defined in audio graph card DT node. I checked other DTs which are using CS42L51 codec (armada-370-db.dts kirkwood-openrd-client.dts, kirkwood-openrd-ultimate.dts),but I did not find reference to "Mic Bias" widget. So, my understanding is that the patch should not break the legacy. If you think this assumption is not correct please let me know.
