From c8f54918eece907f904d160815603bfcee0cfa1e Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 15 Dec 2021 10:51:16 +0100 Subject: [PATCH] drm/vc4: Remove conflicting framebuffers before callind bind_all The bind hooks will modify their controller registers, so simplefb is going to be unusable anyway. Let's avoid any transient state where it could still be in the system but no longer functionnal.
