[PATCH v4 00/19] Introduce support for MediaTek MT8192 Google Chromebooks

[Nícolas F. R. A. Prado]

This series introduces Devicetrees for the MT8192-based Asurada platform
as well as Asurada Spherion and Asurada Hayato boards.

Support for the boards is added to the extent that is currently enabled
in the mt8192.dtsi, and using only properties already merged in the
dt-bindings, as to not add any dependencies to this series.

This series was peer-reviewed internally before submission.

Series tested on next-20220629.
