But I disliked the fact that then mvneta will exploit the knowledge of the fact that of_phy_register_fixed_link() uses a fixed_phy driver. What if the implementation will later change? Also what makes me uncomfortable is that since of_phy_register_fixed_link() doesn't even return the struct phy_device pointer, mvneta will have to get around that and use for example of_phy_find_device(), or register the callback later, after of_phy_connect(). dsa/slave.c does of_phy_connect() initially, together with fixed link registration, so it gets around the problem. But mvneta registers the fixed_link in .probe callback, and does of_phy_connect() in .open callback. This all made me to drop that idea despite the simplicity. >> This will remove a few changes indeed, but perhaps not too much. >> Please confirm if this is exactly what you want, and then I try. > Let me know if this is clearer now, if not, I can certainly cook a > patch which does what I am suggesting. Thanks! I can do that too, because I already did. Let me know if the above concerns are not important, and I'll restore my initial patch. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
