From d1ced662ff5ed90a489b6610144d480bfd7a64e9 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 6 Jan 2020 18:21:44 +0100 Subject: [PATCH] drm/vc4: hdmi: Move accessors to vc4_hdmi The current driver only supports a single HDMI controller, and part of the issue is that the main vc4_dev structure holds a pointer to its (only) HDMI controller, and the HDMI registers accessors will use it to retrieve the mapped addresses. Let's modify those accessors to use directly the vc4_hdmi structure so that we can eventually get rid of that single global pointer.
