Thank you for the comments.

I used anyOf to mention that the compatible strings can be either used
separately or together in the DT files after referring [1].

Using enum brought in constraints such as if one compatible string is
used the other cannot be used.

The error that I made was use of '\t' at the start of the lines. I will
correct it and send a respin.
