Ah, right, that was to reflect the clock domain situation so that someday when I get time to do device power management the kernel can know that by shutting down ether...@25000 it's also shutting down m...@24520, which is also used by ether...@26000. Adding simple-bus was a bit of a hack, but it preserves the existing binding whereby mdio sits under a simple-bus. Ideally, the mdio node would simply be a container for PHY nodes, and would simply be a part of gianfar rather than a separate entity. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
