Yeah, it is final, but not all of the display-related nodes in mt8192.dtsi have
been merged yet [1] and I didn't want to introduce dependencies to the series.

If that series gets merged before this one, I could add the display to this
series as well, but I'm just worried that by introducing new commits with almost
every new series version, this series might never get reviewed and merged, and
this series is pretty big already. So I'd prefer to leave the display for a
following series.

Thanks,
Nícolas
