From ef65a6f064b3bd497d83b0f40908182ba2a2b863 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Date: Wed, 21 Oct 2020 18:34:56 +0100
Subject: [PATCH] drm/vc4: Add all the HDMI registers into the debugfs
dumps
The vc5 HDMI registers hadn't been added into the debugfs
register sets, therefore weren't dumped on request.
Add them in.
