Hi,

Thanks for the patch. Please use get_maintainers.pl to get the list of
folks to Cc. You missed Rob. This is even weirder because you put him as
a maintainer...

This should not be Rob but someone responsible for the driver. I see
there is no maintainers entry, so put there me:

Drop pinctrl, there is a typo here and this is already provided by the
schema.

Use 4-space indentation for the example. Easier to read.
