+The node for this driver must be a child node of a SPI controller,
hence
+all mandatory properties described in
+
+        Documentation/devicetree/bindings/spi/spi-bus.txt

+Required properties:
+ 	- compatible:  	Must be one of the following, depending on the
+                 	model:

+				"mcp3004"
+				"mcp3008"
+				"mcp3201"
+				"mcp3202"
+				"mcp3204"
+				"mcp3208"
+
+
+Examples:
+spi_controller {
+	mcp3x0x@0 {
+		compatible = "mcp3002";
+		reg = <0>;
+		spi-max-frequency = <1000000>;
