description: |
  Qualcomm QCA8072/5 Ethernet PHY is PHY package of 2 or 5
  IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and
  1000BASE-T PHY-s.
 
  They feature 2 SerDes, one for PSGMII or QSGMII connection with
  MAC, while second one is SGMII for connection to MAC or fiber.
 
  Both models have a combo port that supports 1000BASE-X and
  100BASE-FX fiber.
 
  Each PHY inside of QCA807x series has 4 digitally controlled
  output only pins that natively drive LED-s for up to 2 attached
  LEDs. Some vendor also use these 4 output for GPIO usage without
  attaching LEDs.
 
  Note that output pins can be set to drive LEDs OR GPIO, mixed
  definition are not accepted.

      PHY package can be configured in 3 mode following this table:

                    First Serdes mode       Second Serdes mode
      Option 1      PSGMII for copper       Disabled
                    ports 0-4
      Option 2      PSGMII for copper       1000BASE-X / 100BASE-FX
                    ports 0-4
      Option 3      QSGMII for copper       SGMII for
                    ports 0-3               copper port 4
 
      PSGMII mode (option 1 or 2) is configured dynamically based on
      the presence of a connected SFP device.

          With this not defined, bias current tweak are enabled
          by default.
 
          With this enabled the following tweak are NOT applied:
          - With both FULL amplitude and FULL bias current: bias current
            is set to half.
          - With only DSP amplitude: bias current is set to half and
            is set to 1/4 with cable < 10m.
          - With DSP bias current (included both DSP amplitude and
            DSP bias current): bias current is half the detected current
            with cable < 10m.
