Hello maintainers,

I have tested this series (and its dependencies - where [1] is needed to even
be able to apply this one) on multiple machines featuring different MediaTek
SoCs and everything works as expected on both oldies and new ones.

I want to make sure you know that series [1] is also fine and has R-b tags,
apart from the first commit (1/8) that in my opinion should be removed (or
simply ignored while applying, as it's not impacting on any other change in
that series, nor in this one).

In my opinion, the two (vdosys0 and 1) series are ready to be picked.

Thank you all,
Angelo
