Subject: [net-next PATCH RFC v3 6/8] dt-bindings: net: Document Qcom QCA807x PHY package
Document Qcom QCA807x PHY package.
Qualcomm QCA807X Ethernet PHY is PHY package of 2 or 5
IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and
1000BASE-T PHY-s.
Document the required property to make the PHY package correctly
configure and work.

+description: |
+ Qualcomm QCA807X 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
