Subject: [net-next PATCH v5 6/9] 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
