Subject: [PATCH] ahci: qoriq: Revert "ahci: qoriq: Disable NCQ on ls2080a SoC"
Date: Wed, 28 Sep 2016 09:46:12 +0800	[thread overview]
Message-ID: <1475027172-21012-1-git-send-email-yuantian.tang@nxp.com> (raw)

From: Tang Yuantian <Yuantian.Tang@nxp.com>

This reverts commit 640847298e2b7f19 ("ahci: qoriq: Disable NCQ
on ls2080a SoC")

The erratum has been fixed in ls2080a v2.0 and later soc.
Since ls2080a v1.0 has rarely been released, it can be safely
reverted.
