Whole series is both

Tested-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com> 
#MT8196 Chromebook

and is also

Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

...and besides, this got also tested on MT8188/95 in our lab (for quite a while).
