From 8907c2c50408b39e93fb42b2d74ab908480320a0 Mon Sep 17 00:00:00 2001 From: Eric Nelson Date: Tue, 20 Aug 2013 11:44:43 -0700 Subject: i.MX6: nitrogen6x: force HDMI onto IPU0/DI0 Our Linux kernel switches the HDMI connector onto IPU0/DI1, but the U-Boot display driver only supports IPU0/DI0 for the time being. Because of this, a soft re-boot will leave the HDMI output connected to the wrong display port and prevent video from being displayed.
