This is purely a rebased of Nicolas's v3 patch set from around a year ago.

I've tested this using mesa 21.3.x and Wayland/Gnome on Fedora 35, it's 
more or less stable with basic testing.

Hi,

The downstream tree [1] uses 'brcm,2711-v3d'. Is there a reason for not
using the same compatible string ? Having the same string would allow
using downstream dtbs (and overlays) with the upstream kernel.
