Subject: Re: [PATCH 2/7] dt-bindigns: regulator: mtk: Drop unneeded compatible

Hi Matthias,

Thank you for your patch. There is a typo in the subject line
s/dt-bindigns/dt-bindings/ Rob might miss this patch as he filters the
patches by subject I guess.

If you convert this binding to YAML, you'll probably get a review that
the node name must be just 'regulators' here. And then, looking at the
other patches something will break I guess ...
