From 0dd9721f26df2b767f32042afb17bb7baf09c633 Mon Sep 17 00:00:00 2001
From: Dalon Westergreen <dwesterg@gmail.com>
Date: Sun, 12 Feb 2017 15:03:53 -0800
Subject: [PATCH 4/6] Add HDMI init to de10 env
This uses stand alone applications to probe the EDID data
of the connected monitor and uses that information to
setup the FPGA's HDMI pll as well as add the appropriate
devicetree node to the devicetree
