Subject: ARM: dts: imx6ul-14x14-evk: update TX D_CAL for USBPHY
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=901725b7902eb776df0b4d83e5210e2bcd1bd9ce;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: imx6ul-14x14-evk: update TX D_CAL for USBPHY

We need to change trimming value (as a percentage) of the 17.78mA TX
reference current for better signal quality. With this change, we
can pass the eye-diagram test on this board.
