The ADIN1100 uses Auto-Negotiation capability in accordance with IEEE 802.3 Clause 98, providing a mechanism for exchanging information between PHYs to allow link partners to agree to a common mode of operation. The concluded operating mode is the transmit amplitude mode and master/slave preference common across the two devices. Both device and LP advertise their ability and request for increased transmit at: - BASE-T1 autonegotiation advertisement register [47:32]\ Clause 45.2.7.21 of Standard 802.3 - BIT(13) - 10BASE-T1L High Level Transmit Operating Mode Ability - BIT(12) - 10BASE-T1L High Level Transmit Operating Mode Request For 2.4 Vpp (high level transmit) operation, both devices need to have the High Level Transmit Operating Mode Ability bit set, and only one of them needs to have the High Level Transmit Operating Mode Request bit set. Otherwise 1.0 Vpp transmit level will be used.

Add basic support for ADIN1100. Alexandru Ardelean (1): net: phy: adin1100: Add initial support for ADIN1100 industrial PHY 1. Added 10baset-T1L link modes. 2. Added 10-BasetT1L registers. 3. Added Base-T1 auto-negotiation registers. For Base-T1 these registers decide master/slave status and TX voltage of the device and link partner. 4. Added 10BASE-T1L support in phy-c45.c. Now genphy functions will call Base-T1 functions where registers don't match, like the auto-negotiation ones. 5. Convert MSE to SQI using a predefined table and allow user access through ethtool. 6. DT bindings for the 2.4 Vpp transmit mode.
