Subject: [PATCH 11/12] ARM: imx6: change default burst size for USB
Date: Thu, 19 Mar 2015 09:19:22 +0800 [thread overview]
Message-ID: <1426727963-32280-12-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1426727963-32280-1-git-send-email-peter.chen@freescale.com>
It can improve the USB performance when choosing larger
burst size at some systems (bus size is larger), there is
no side effect if this burst size is larger than bus size.
