-From 4f09499bc1d9bb095caccbcd73ff951ee631e521 Mon Sep 17 00:00:00 2001
-From: Mathieu Olivari <mathieu@codeaurora.org>
-Date: Fri, 8 May 2015 15:42:40 -0700
-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.
-
-Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org>

-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.

-From: Mathieu Olivari <mathieu@codeaurora.org>
-Date: Fri, 8 May 2015 15:57:12 -0700
-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:
-Documentation/devicetree/bindings/net/fixed-link.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>;
-+ qcom,qsgmii-csr = <&qsgmii_csr>;
-+
-+ clocks = <&gcc GMAC_CORE1_CLK>;
-+ clock-names = "stmmaceth";
-+
-+ resets = <&gcc GMAC_CORE1_RESET>;
-+ reset-names = "stmmaceth";
-+ };
