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 is set to DSP.
(bias current is adjusted based on cable length)
Actual bias current might be different with

description: |
Set Analog MDI driver bias current to disable tweak
to bias current.
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.
