Subject: [PATCH 4.16 13/26] drm/i915/audio: Fix audio detection issue on GLK
Date: Wed, 25 Apr 2018 12:33:22 +0200 [thread overview]
Message-ID: <20180425103315.374964303@linuxfoundation.org> (raw)
In-Reply-To: <20180425103314.842517924@linuxfoundation.org>
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gaurav K Singh <gaurav.k.singh@intel.com>
commit b4615730530be85fc45ab4631c2ad6d8e2d0b97d upstream.
On Geminilake, sometimes audio card is not getting
detected after reboot. This is a spurious issue happening on
Geminilake. 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 GLK. Extending this fix to GLK as well.
Tested by Du,Wenkai on GLK board.
Bspec: 21829
v2: Instead of checking GEN9_BC, BXT and GLK macros, use IS_GEN9 macro (Jani N)
