From 5adc56d40514082dec053b4777cefa742bb0aad0 Mon Sep 17 00:00:00 2001
From: Josip Pavic <Josip.Pavic@amd.com>
Date: Tue, 8 Jan 2019 14:43:10 -0500
Subject: [PATCH 1142/2940] drm/amd/display: Update DMCU versioning mechanism
[Why]
Current date based versioning doesn't tell us about feature version
and build version, and is not useful for debug.
[How]
Add versioning based on feature and build
