You list one string here, but there's 2 in the example. The point of
this exercise was to document (not just in an Example) the strings
you're using.
Ok, will do.

Really? That was barely useful in the rk3399-gru DTSI, but it's
definitely not worth sticking in an example.

Also, you switch between tabs and spaces for indentation. Please be
consistent. (And as with C code, I think the right answer is tabs?)
Oops, thanks for noticing.

Example != Documentation. Please document the string properly.
Ok, will do.
