Merge branch 'Socionext-Synquacer-NETSEC-driver'

Jassi Brar says:

====================
Socionext Synquacer NETSEC driver

Changes since v5
	# Removed helper macros
	# Removed 'inline' qualifier
	# Changed multiline empty comment to single line
	# Added 'clock-names' property in DT binding example
	# Ignore 'clock-names' property in driver until f/ws in the wild are
	  upgraded or we support instance that take in more than one clock.
	# Rebased the patchset onto net-next

Changes since v4
        # Fixed ucode indexing as a word, instead of byte
        # Removed redundant clocks, keep only phy rate reference clock
          and expect it to be 'phy_ref_clk'

Changes since v3
        # Discard 'socionext,snq-mdio', and simply use 'mdio' subnode.
        # Use ioremap on ucode region as well, instead of memremap.

Changes since v2
        # Use 'mdio' subnode in DT bindings.
        # Use phy_interface_mode_is_rgmii(), instead of open coding the check.
        # Use readl/b with eeprom_base pointer.
        # Unregister mdio bus upon failure in probe.

Changes since v1
        # Switched from using memremap to ioremap
        # Implemented ndo_do_ioctl callback
        # Defined optional 'dma-coherent' DT property

+* Socionext NetSec Ethernet Controller IP
+
+Required properties:
+- compatible: Should be "socionext,synquacer-netsec"
+- reg: Address and length of the control register area, followed by the
+       address and length of the EEPROM holding the MAC address and
+       microengine firmware
+- interrupts: Should contain ethernet controller interrupt
+- clocks: phandle to the PHY reference clock
+- clock-names: Should be "phy_ref_clk"
+- phy-mode: See ethernet.txt file in the same directory
+- phy-handle: See ethernet.txt in the same directory.
+
+- mdio device tree subnode: When the Netsec has a phy connected to its local
+		mdio, there must be device tree subnode with the following
+		required properties:
+
+	- #address-cells: Must be <1>.
+	- #size-cells: Must be <0>.
+
+	For each phy on the mdio bus, there must be a node with the following
+	fields:
+	- compatible: Refer to phy.txt
+	- reg: phy id used to communicate to phy.
+
+Optional properties: (See ethernet.txt file in the same directory)
+- dma-coherent: Boolean property, must only be present if memory
+	accesses performed by the device are cache coherent.
+- local-mac-address: See ethernet.txt in the same directory.
+- mac-address: See ethernet.txt in the same directory.
+- max-speed: See ethernet.txt in the same directory.
+- max-frame-size: See ethernet.txt in the same directory.
+
+Example:
+	eth0: ethernet@522d0000 {
+		compatible = "socionext,synquacer-netsec";
+		reg = <0 0x522d0000 0x0 0x10000>, <0 0x10000000 0x0 0x10000>;
+		interrupts = <GIC_SPI 176 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&clk_netsec>;
+		clock-names = "phy_ref_clk";
+		phy-mode = "rgmii";
+		max-speed = <1000>;
+		max-frame-size = <9000>;
+		phy-handle = <&phy1>;
+
+		mdio {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			phy1: ethernet-phy@1 {
+				compatible = "ethernet-phy-ieee802.3-c22";
+				reg = <1>;
+			};
+		};
