[PATCH v3 00/14] net: phy: adin: add support for Analog Devices PHYs

From: Alexandru Ardelean
Date: Fri Aug 09 2019 - 09:36:12 EST

This changeset adds support for Analog Devices Industrial Ethernet PHYs.
Particularly the PHYs this driver adds support for:
* ADIN1200 - Robust, Industrial, Low Power 10/100 Ethernet PHY
* ADIN1300 - Robust, Industrial, Low Latency 10/100/1000 Gigabit
Ethernet PHY

The 2 chips are pin & register compatible with one another. The main
difference being that ADIN1200 doesn't operate in gigabit mode.

The chips can be operated by the Generic PHY driver as well via the
standard IEEE PHY registers (0x0000 - 0x000F) which are supported by the
kernel as well. This assumes that configuration of the PHY has been done
completely in HW, according to spec, i.e. no extra SW configuration

This changeset also implements the ability to configure the chips via SW
