Huh?

What is this a binding for? From a look at the driver in mainline this
just calls into functions from the twl4030 madc driver (which doesn't
seem to have a binding).

This doesn't look like a description of hardware, but rather a hack to
get a Linux driver to probe. As far as I can see, no useful information
is given by this binding.

Thanks,
Mark.
