How about this:
<function> := one of [serial, spi, i2s, ac97]
<function>@<psc_offset> {
port-number = <logical port number>; // so /dev/ttyPSC#
connects to something sane
compatible = "mpc5200b-psb\0mpc52xx-psc";
... other stuff ...
};
Function is encoded in the node name, and the compatible property
tells linux that it is an mpc52xx-psc in <function> mode.
