-Subject: [PATCH 10/13] drm/i915: Fix audio power up sequence for gen10+
- display
-
-On platfroms with gen10+ display, driver must set the enable bit of
-AUDIO_PIN_BUF_CTL register before transactions with the HDA controller
-can proceed. Add setting this bit to the audio power up sequence.
-
-Failing to do this resulted in errors during display audio codec probe,
-and failures during resume from suspend.
-
-Note: We may also need to disable the bit afterwards, but there are
-still unresolved issues with that.
