Nice helper function, indeed.

Just a quick question about the use of the "phy-mode" string: 
- I know that it is widely used in drivers
- but, I discovered that in the ePAPR the string mentioned is "phy-connection-type" (6.5.2.2)
- and it is true also that in the very same document, we find the "phy-mode" in the Appendix B1 example...

Why this naming is not consistent (even in ePAPR)?
