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 2/8] stmmac: move error path at the end of
stmmac_probe_config_dt()
We will want to do additional clean-up on certain errors. Therefore,
this change moves the error path at the end of the function for better
code readability.
This patch doesn't change anything functionally.

detect a fixed-link PHY, instanciate it, and use it during
phy_connect().
Fixed link PHYs DT usage is described in:

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>;

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.

Subject: [PATCH 2/8] stmmac: move error path at the end of
stmmac_probe_config_dt()
We will want to do additional clean-up on certain errors. Therefore,
this change moves the error path at the end of the function for better
code readability.
This patch doesn't change anything functionally.

Subject: [PATCH 3/8] stmmac: add fixed-link device-tree support
In case DT is used, this change adds the ability to the stmmac driver to
detect a fixed-link PHY, instanciate it, and use it during
phy_connect().
Fixed link PHYs DT usage is described in:

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>;
+ qcom,qsgmii-csr = <&qsgmii_csr>;
+
+ clocks = <&gcc GMAC_CORE1_CLK>;
+ clock-names = "stmmaceth";
+
+ resets = <&gcc GMAC_CORE1_RESET>;
+ reset-names = "stmmaceth";
+ };
