From 847ec495822ad512dd9f1a58a85dabea01534855 Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime@cerno.tech>

Subject: [PATCH] drm/vc4: drv: Support BCM2712
The BCM2712 has an improved display pipeline, most notably with a
different HVS and only HDMI and writeback outputs.
Let's introduce it as a new VideoCore generation and compatible.
