Subject: ARM: dts: imx6: set ahb-burst-config as 0 for USB
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9493bf5458e936b88e5d3a33f9ed09bc5c1263b0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: imx6: set ahb-burst-config as 0 for USB

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