The commit message here doesn't make much sese, you're adding a new
file. Something like the description in the binding below would be a
better fit than what you have.

^^^^^^^^^^^^
If this is not part of your name, or a client of Bosch that you want to
attribute authorship to, remove it.

You can, drop this, don't think it's worth mentioning in the
description.

I think the descriptions for these are not really worth having and can
be replaced with "vddio-supply: true" etc.

However, the supplies likely are required to function and should be
added to the required section.

You have trailing whitespace after this line.
