Subject: [PATCH 02/12] usb: phy-mxs: Enable IC fixes for mx6 SoC serial
Date: Sat, 12 Oct 2013 17:09:36 +0800	[thread overview]
Message-ID: <1381568986-19802-3-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1381568986-19802-1-git-send-email-peter.chen@freescale.com>

After adding IC fixes bits, some PHY bugs are fixed by
IC logic.
