From 85801579e10208b7466f4a7f8329b4f5d2056fff Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 15 Jun 2016 14:18:37 +0800 Subject: [PATCH] imx6ulevk: fix 74LV OE usage Fix 74LV OE gpio index. gpio index is wrong, so gpio output will not have effect, since we use wrong GPIO5_IO18, but not correct GPIO5_IO8. And at the end of the initialization of 74lv init, should keep OE voltage level at LOW to make 74lv output the correct voltage.
