Subject: Re: [PATCH v21 7/8] arm64: dts: mt8192: add svs device information

Typo: compitable => compatible
.. also, you're not only adding the svs node, but also efuse: please add that
information in the commit description.

This patch seems to not apply on top of the current linux-next, can you please
rebase it? That would resolve issues with this series and would be picked sooner.

Apart from that...
