According to new (though still not approved) bindings, this should

For new bindings I changed this to "voltage-ranges", so that we
could specify discontinuous range.

device_type isn't needed.

OK, will remove.

According to new (though still not approved) bindings, this should
be "<board-specific>-mmc-slot", "mmc-spi-slot".

So I will wait a while with re-sending until this is "approved".

OK, will change in next version.

Thanks.
