14  Qualcomm QCA8072/5 Ethernet PHY is PHY package of 2 or 5
15  IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and
16  1000BASE-T PHY-s.
17
18  They feature 2 SerDes, one for PSGMII or QSGMII connection with
19  MAC, while second one is SGMII for connection to MAC or fiber.
20
21  Both models have a combo port that supports 1000BASE-X and
22  100BASE-FX fiber.
23
24  Each PHY inside of QCA807x series has 4 digitally controlled
25  output only pins that natively drive LED-s for up to 2 attached
26  LEDs. Some vendor also use these 4 output for GPIO usage without
27  attaching LEDs.
28
29  Note that output pins can be set to drive LEDs OR GPIO, mixed
30  definition are not accepted.

52      PSGMII mode (option 1 or 2) is configured dynamically based on
53      the presence of a connected SFP device.

109          - With DSP bias current (included both DSP amplitude and
110            DSP bias current): bias current is half the detected current
111            with cable < 10m.
