-* Wiznet w5x00
-
-This is a standalone 10/100 MBit Ethernet controller with SPI interface.
-
-For each device connected to a SPI bus, define a child node within
-the SPI master node.
-
-Required properties:
-- compatible: Should be one of the following strings:
-	      "wiznet,w5100"
-	      "wiznet,w5200"
-	      "wiznet,w5500"
-- reg: Specify the SPI chip select the chip is wired to.
-- interrupts: Specify the interrupt index within the interrupt controller (referred
-              to above in interrupt-parent) and interrupt type. w5x00 natively
-              generates falling edge interrupts, however, additional board logic
-              might invert the signal.
-- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
-- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
-             see also generic and your platform specific pinctrl binding
-             documentation.
-
-Optional properties:
-- spi-max-frequency: Maximum frequency of the SPI bus when accessing the w5500.
-  According to the w5500 datasheet, the chip allows a maximum of 80 MHz, however,
-  board designs may need to limit this value.
-- local-mac-address: See ethernet.txt in the same directory.
-
-
-Example (for Raspberry Pi with pin control stuff for GPIO irq):
-
-&spi {
-	ethernet@0: w5500@0 {
-		compatible = "wiznet,w5500";
-		reg = <0>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&eth1_pins>;
-		interrupt-parent = <&gpio>;
-		interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
-		spi-max-frequency = <30000000>;
-	};
-};
-
-&gpio {
-	eth1_pins: eth1_pins {
-		brcm,pins = <25>;
-		brcm,function = <0>; /* in */
-		brcm,pull = <0>; /* none */
-	};
-};
