+Subject: net: phy: qcom: at803x: Add Qualcomm IPQ5018 Internal PHY support
+
+The IPQ5018 SoC contains a single internal Gigabit Ethernet PHY which
+provides an MDI interface directly to an RJ45 connector or an external
+switch over a PHY to PHY link.
+
+The PHY supports 10BASE-T/100BASE-TX/1000BASE-T link modes in SGMII
+interface mode, CDT, auto-negotiation and 802.3az EEE.
+
+Let's add support for this PHY in the at803x driver as it falls within
+the Qualcomm Atheros OUI.

+
+IPQ5018 contains two mdio buses of which one bus is used to control the
+SoC's internal GE PHY, while the other bus is connected to external PHYs
+or switches.
+
+There's already support for IPQ5018 in the mdio-ipq4019 driver, so let's
+simply add the mdio nodes for them.

+Subject: arm64: dts: qcom: ipq5018: Add GE PHY to internal mdio bus
+
+The IPQ5018 SoC contains an internal GE PHY, always at phy address 7.
+As such, let's add the GE PHY node to the SoC dtsi.
+
+The LDO controller found in the SoC must be enabled to provide constant
+low voltages to the PHY. The mdio-ipq4019 driver already has support
+for this, so adding the appropriate TCSR register offset.
+
+In addition, the GE PHY outputs both the RX and TX clocks to the GCC
+which gate controls them and routes them back to the PHY itself.
+So let's create two DT fixed clocks and register them in the GCC node.

-Subject: [PATCH v3 3/5] net: phy: qcom: at803x: Add Qualcomm IPQ5018 Internal PHY support
-MIME-Version: 1.0
-Content-Type: text/plain; charset="utf-8"
-Content-Transfer-Encoding: 7bit
-
-The IPQ5018 SoC contains a single internal Gigabit Ethernet PHY which
-provides an MDI interface directly to an RJ45 connector or an external
-switch over a PHY to PHY link.
-
-The PHY supports 10/100/1000 mbps link modes, CDT, auto-negotiation and
-802.3az EEE.
-
-Let's add support for this PHY in the at803x driver as it falls within
-the Qualcomm Atheros OUI.

-MIME-Version: 1.0
-Content-Type: text/plain; charset="utf-8"
-Content-Transfer-Encoding: 7bit
-
-IPQ5018 contains two mdio buses of which one bus is used to control the
-SoC's internal GE PHY, while the other bus is connected to external PHYs
-or switches.
-
-There's already support for IPQ5018 in the mdio-ipq4019 driver, so let's
-simply add the mdio nodes for them.

-Subject: [PATCH v3 5/5] arm64: dts: qcom: ipq5018: Add GE PHY to internal mdio bus
-MIME-Version: 1.0
-Content-Type: text/plain; charset="utf-8"
-Content-Transfer-Encoding: 7bit
-
-The IPQ5018 SoC contains an internal GE PHY, always at phy address 7.
-As such, let's add the GE PHY node to the SoC dtsi.
-
-The LDO controller found in the SoC must be enabled to provide constant
-low voltages to the PHY. The mdio-ipq4019 driver already has support
-for this, so adding the appropriate TCSR register offset.
-
-In addition, the GE PHY outputs both the RX and TX clocks to the GCC
-which gate controls them and routes them back to the PHY itself.
-So let's create two DT fixed clocks and register them in the GCC node.
