I was able to use this code to find the lmu-controller node and read the address from 'reg' - looks like it's the value shifted right one bit. (An old posting[1] does it similarly.) But I can't work out how to get the bus number (probed as 8 on my machine). The linked patch tries to use the last bit of 'reg', but that can't be right.
