+Micrel KS8995 SPI controlled Ethernet Switch families
+
+Required properties (according to spi-bus.txt):
+- compatible: either "micrel,ks8995", "micrel,ksz8864" or "micrel,ksz8795"
+
+Optional properties:
+- settings: list of register initialization triples containing
+            register offset, register value and register mask.
+- reset-gpios : phandle of gpio that will be used to reset chip during probe
+
+Example:
+
+spi-master {
+	...
+	ksz8795 {
+		compatible = "micrel,ksz8795";
+
+		reg = <0>;
+		spi-max-frequency = <50000000>;
+		settings = <
+			0x56 0x10 0x10 /* Enable Ingress RGMII-ID Mode */
+			0x3D 0x08 0x08 /* power down port 3 */
+			0x4D 0x08 0x08 /* power down port 4 */
+		>;
+		reset-gpios = <&gpio0 46 1>;
