From b651bd2a3ae33f6a98d6ea36ef2518f5211bdc4f Mon Sep 17 00:00:00 2001 From: Gaurav K Singh Date: Thu, 5 Apr 2018 22:12:24 +0530 Subject: [PATCH] drm/i915/audio: Fix audio enumeration issue on BXT On Apollolake, with stress test warm reboot, audio card was not getting enumerated after reboot. This was a spurious issue happening on Apollolake. HW codec and HD audio controller link was going out of sync for which there was a fix in i915 driver but was not getting invoked for BXT. Extending this fix to BXT as well. Tested on apollolake chromebook by stress test warm reboot with 2500 iterations.
