You need to remove bindings/mips/brcm/brcm,bmips.txt. But it also 
defines a property which needs to be added.

I didn't check the rest for existing documentation...

I have addressed this in v2:

The rest of compatible strings for cpu's that I am listing here seems
to not contain associated txt bindings description, so I guess if
anything extra is needed / required can be added afterwards?

Thanks,
