Subject: [PATCH 05/10] ARM: imx6: set ahb-burst-config as 0 for USB
Date: Wed, 29 Jul 2015 10:42:09 +0800 [thread overview]
Message-ID: <1438137734-27311-6-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1438137734-27311-1-git-send-email-peter.chen-KZfg59tc24xl57MIdRCFDg@public.gmane.org>
After setting ahb burst configuration as 0, we can increase tx/rx
burst size, it will improve the USB performance
