From 7aa9189e401ddee705d851fe30b59d81cc71ebac Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>

Subject: [PATCH] drm/vc4: crtc: Don't call into BO Handling on Async
Page-Flips on BCM2711
The BCM2711 doesn't have a v3d GPU so we don't want to call into its BO
management code. Let's create an asynchronous page-flip handler for the
BCM2711 that just calls into the common code.
