From 44a2a4f524a53bfce1c88582d294bc30ad9062bf Mon Sep 17 00:00:00 2001 From: Dave Stevenson 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.
