You can take a look at:

commit a8c21a5451d831e67b7a6fb910f9ca8bc7b43554
Author: The etnaviv authors <dri-devel at lists.freedesktop.org>
Date:   Thu Dec 3 18:21:29 2015 +0100

    drm/etnaviv: add initial etnaviv DRM driver

    This adds the etnaviv DRM driver and hooks it up in Makefiles
    and Kconfig.
