Ah, excellent, so a small quirk in i2c_powermac is the way to go then, we can detect it by name and hack up something. Either that or even better, in prom_init, we could add the missing property to the device-tree. Any chance you can try that ? (Look at other examples of DT fixups in prom_init.c and don't forget the RELOC() around strings :-) Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
