It's probably a good idea to put some comment in the code to that effect - people don't generally look at the history when adding new features. It's probably also a good idea to claim the GPIO for the PHY power control and ensure that it's set to 'off' mode - that code can then be a placeholder for the comment. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
