I think *requiring* a binding to ethernet devices is a bad idea. For example, on many MPC8260 embedded systems, the MII bus is controlled by GPIO pins, not an ethernet MDIO system. Some applications may use the MII bus to control non-PHY devices, such as Broadcom ethernet switches. I'm working for a general MII bus that ethernet PHYs and other devices can all use. -- Jason McMullan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
