Subject: [PATCH v2 05/13] ALSA: hdac: Increase timeout value for link power check
Date: Sat, 12 Dec 2015 17:36:25 +0530 [thread overview]
Message-ID: <1449921993-21101-6-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1449921993-21101-1-git-send-email-vinod.koul@intel.com>
From: Jayachandran B <jayachandran.b@intel.com>
HW recommends 180us for worst case values for link power up
delay, so change the current delay value from 50 (150us) to 150
(450us)
