You mean no "in-kernel" DTS. But my question was if any DTS in the world may
supply this as AVDD? If answer is yes, the binding must be changed. But then
the same issue may come due to somebody using a new binding somewhere. however
I don't understand how in that case it will work in Linux (only other projects
that use the same bindings as Linux kernel may be affected).

I think this sounds at least like a safer change.
