MFD isn't a thing.  We made it up.  Please describe it as it is in the datasheet.

Its a I2C controller node, I don't think address is needed. Mention like 
this my previous other driver patches,

dt_binding_check is also passed

Rob, why are these here if they just result in 404s?

This doesn't sound right.

How do you control/operate the controller?

Surely you read/write from/to registers?

Indeed, but each SoC will have different address so which address to 
mention here.
For me it should be like &i2c {}, anyhow I respect maintainers review (I 
can give RPi I2c bus address used for testing)
and wait for Rob's reply

It's only an example.  It doesn't have to match any real H/W.
