From 25eb441d55d479581a65bcc9de88bc1d86bf76c1 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 13 Jun 2022 16:47:45 +0200 Subject: [PATCH] drm/vc4: hdmi: Add all the vc5 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.
