Yes, very much. Aside from the kernel-side implementation all we need is
the userspace per
https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#open-source-userspace-requirements
Important: Don't merge the userspace side into your main branch before
it's all reviewed.
And ideally some igts (we have infrastructure to inject edids and hence
can check that the right stuff comes back):
