+Subject: [PATCH] Revert "Revert "drm/vc4: Force HDMI to connected.""
+
+This reverts commit 7da44d06540b4a191ecc74e943f3203577fce0df.
+
+This breaks the driver on Pi3 as hotplug is implemented through a
+gpio expander owned by the GPU.
+
+We need to extend the virtual gpio driver to support this, but for
+now assume hotplug is always enabled.
