Subject: ARM: dts: imx6: change default burst size for USB
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2b1a40e8d182a9f7779ba4fe54c5b73980c215b0;p=linux.git

ARM: dts: imx6: change default burst size for USB

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.
