+Subject: [PATCH 1/8] stmmac: add phy-handle support to the platform layer
+
+On stmmac driver, PHY specification in device-tree was done using the
+non-standard property "snps,phy-addr". Specifying a PHY on a different
+MDIO bus that the one within the stmmac controller doesn't seem to be
+possible when device-tree is used.
+
+This change adds support for the phy-handle property, as specified in
+Documentation/devicetree/bindings/net/ethernet.txt.

+Subject: [PATCH 4/8] stmmac: add ipq806x glue layer
+
+The ethernet controller available in IPQ806x is a Synopsys DesignWare
+Gigabit MAC IP core, already supported by the stmmac driver.
+
+This glue layer implements some platform specific settings required to
+get the controller working on an IPQ806x based platform.

+* IPQ806x DWMAC Ethernet controller
+
+The device inherits all the properties of the dwmac/stmmac devices
+described in the file net/stmmac.txt with the following changes.
+
+Required properties:
+
+- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
+	      and any applicable more detailed version number
+	      described in net/stmmac.txt
+
+- qcom,nss-common: should contain a phandle to a syscon device mapping the
+		   nss-common registers.
+
+- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
+		   qsgmii-csr registers.
+
+Example:
+
+	gmac: ethernet@37000000 {
+		device_type = "network";
+		compatible = "qcom,ipq806x-gmac";
+		reg = <0x37000000 0x200000>;
+		interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-names = "macirq";
+
+		qcom,nss-common = <&nss_common>;

+Subject: [PATCH 6/8] net: stmmac: create one debugfs dir per net-device
+
+stmmac DebugFS entries are currently global to the driver. As a result,
+having more than one stmmac device in the system creates the following
+error:
+* ERROR stmmaceth, debugfs create directory failed
+* stmmac_hw_setup: failed debugFS registration
+
+This also results in being able to access the debugfs information for
+the first registered device only.
+
+This patch changes the debugfs structure to have one sub-directory per
+net-device. Files under "/sys/kernel/debug/stmmaceth" will now show-up
+under /sys/kernel/debug/stmmaceth/ethN/.

+Subject: [PATCH 1/8] stmmac: add phy-handle support to the platform layer
+
+On stmmac driver, PHY specification in device-tree was done using the
+non-standard property "snps,phy-addr". Specifying a PHY on a different
+MDIO bus that the one within the stmmac controller doesn't seem to be
+possible when device-tree is used.
+
+This change adds support for the phy-handle property, as specified in
+Documentation/devicetree/bindings/net/ethernet.txt.

+* IPQ806x DWMAC Ethernet controller
+
+The device inherits all the properties of the dwmac/stmmac devices
+described in the file net/stmmac.txt with the following changes.
+
+Required properties:
+
+- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
+	      and any applicable more detailed version number
+	      described in net/stmmac.txt
+
+- qcom,nss-common: should contain a phandle to a syscon device mapping the
+		   nss-common registers.
+
+- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
+		   qsgmii-csr registers.
+
+Example:
+
+	gmac: ethernet@37000000 {
+		device_type = "network";
+		compatible = "qcom,ipq806x-gmac";
+		reg = <0x37000000 0x200000>;
+		interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-names = "macirq";
+
+		qcom,nss-common = <&nss_common>;
+		qcom,qsgmii-csr = <&qsgmii_csr>;
+
+		clocks = <&gcc GMAC_CORE1_CLK>;
+		clock-names = "stmmaceth";
+
+		resets = <&gcc GMAC_CORE1_RESET>;
+		reset-names = "stmmaceth";

+Subject: [PATCH 6/8] net: stmmac: create one debugfs dir per net-device
+
+stmmac DebugFS entries are currently global to the driver. As a result,
+having more than one stmmac device in the system creates the following
+error:
+* ERROR stmmaceth, debugfs create directory failed
+* stmmac_hw_setup: failed debugFS registration
+
+This also results in being able to access the debugfs information for
+the first registered device only.
+
+This patch changes the debugfs structure to have one sub-directory per
+net-device. Files under "/sys/kernel/debug/stmmaceth" will now show-up
+under /sys/kernel/debug/stmmaceth/ethN/.
