From: Alexandru Tachici <alexandru.tachici@analog.com>

The ADIN1100 is a low power single port 10BASE-T1L transceiver designed for
industrial Ethernet applications and is compliant with the IEEE 802.3cg
Ethernet standard for long reach 10 Mb/s Single Pair Ethernet.

1. 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 10base-T1L voltage levels link modes. 1v is the default TX level.
2.4 V support depends on pin configuration and power supply.

3. Allow user to access error and frame counters through ethtool.

4. Allow user to set the master-slave configuration of ADIN1100.

5. Convert MSE to SQI using a predefined table and allow user access
through ethtool.

6. DT bindings for ADIN1100.

Alexandru Tachici (6):
  ethtool: Add 10base-T1L link mode entries
  ethtool: Add 10base-T1L voltage levels link mode entries
  net: phy: adin1100: Add ethtool get_stats support
  net: phy: adin1100: Add ethtool master-slave support
  net: phy: adin1100: Add SQI support
  dt-bindings: adin1100: Add binding for ADIN1100 Ethernet PHY

Changelog v1 -> v2:
  - Added ETHTOOL_LINK_MODE_10baseT1L_Full_BIT and ETHTOOL_LINK_MODE_10baseT1L_Half_BIT.
  Using only full duplex here as chip supports full duplex only
  - removed .match_phy_device
  - removed link partner advertising of modes not present in the kernel
  - enable/disable only the PCS loopback
  - replaced custom timeout implementations with phy_read_mmd_poll_timeout
  - added link modes for 1.0 V and 2.4 V TX levels
  - removed link change notify
  - check if 2.4v TX level is supported in adin_get_features call and set
  corresponding link mode
