Subject: [PATCH 07/12] ARM: imx6: set ahb-burst-config as 0 for USB
Date: Thu, 19 Mar 2015 09:19:18 +0800	[thread overview]
Message-ID: <1426727963-32280-8-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1426727963-32280-1-git-send-email-peter.chen@freescale.com>

After setting ahb burst configuration as 0, we can increase tx/rx
burst size, it will improve the USB performance
