Subject: [PATCH 2/2] ARM: dts: imx6ul-14x14-evk: update TX D_CAL for USBPHY
Date: Mon, 31 Oct 2016 10:58:29 +0800 [thread overview]
Message-ID: <1477882709-2518-2-git-send-email-peter.chen@nxp.com> (raw)
In-Reply-To: <1477882709-2518-1-git-send-email-peter.chen@nxp.com>
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 patch the eye-diagram test on this board.
