Since this is the devicetree documentation, it will need to be approved by
a devicetree maintainer. Wondering why that didn't happen, I just realized
what you did not copy the devicetree mailing list. Please do that when you
resend.
Note that they may require devicetree documentation in yaml format nowadays.
