From 67cb5d52ea2c3ae35d637ab79a46cd452d1c7d41 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Mon, 31 Oct 2016 10:58:28 +0800 Subject: [PATCH] ARM: dts: imx6sx-sdb: 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.
