From 0d7cdc2abfc34125f0bc85f864d285f06675290a Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 15 Jun 2016 14:18:39 +0800 Subject: [PATCH] imx: mx6ulevk: change QSPI PAD DSE to 120ohm The current pad DSE for QSPI is 60ohm. This setting cause too strong drive to clock and data signals. Need to change the DSE to 120ohm for better signal quality.
