To answer my own question:

The entry in the *.dts NEEDS TO REFER TO "ALTR" first.

pcm2par_av_0: unknown@0x09004c0 {

compatible = "ALTR, pcm2par-10.1" "ALTR, pcm2par-1.0";

reg = < 0x09004c0 0x00000010 >;

interrupt-parent = < &cpu >;

interrupts = < 8 >;

}; // end unknown@0x09004c0 (pcm2par_av_0)

Then all is well and the driver is happy.
