This patch adds basic support for BASE-T1 PHYs in the framework. BASE-T1 PHYs main area of application are automotive and industrial. BASE-T1 is standardized in IEEE 802.3, namely - IEEE 802.3bw: 100BASE-T1 - IEEE 802.3bp 1000BASE-T1 - IEEE 802.3cg: 10BASE-T1L and 10BASE-T1S
There are no products which contain BASE-T1 and consumer type PHYs like 1000BASE-T. However, devices exist which combine 100BASE-T1 and 1000BASE-T1 PHYs with auto-negotiation. The intention of this patch is to make use of the existing Clause 45 functions. BASE-T1 adds some additional registers e.g. for aneg control, which follow a similiar register layout as the existing devices. The bits which are used in BASE-T1 specific registers are the same as in basic registers, thus the existing functions can be resued, with get_aneg_ctrl() selecting the correct register address. The current version of ethtool has been prepared for 100/1000BASE-T1 and works with this patch. 10BASE-T1 needs to be added to ethtool.
