+J-Core SPI master
+
+Required properties:
+
+- compatible: Must be "jcore,spi2".
+
+- reg: Memory region for registers.
+
+- #address-cells: Must be 1.
+
+- #size-cells: Must be 0.
+
+Optional properties:
+
+- clock-frequency: Specifies an input clock frequency relative to
+  which the SPI clock speed must be programmed. Necessary only if
+  the input clock rate is something other than 50 MHz.
+
+See spi-bus.txt for additional properties not specific to this device.
+
+Example:
+
+spi@40 {
+	compatible = "jcore,spi2";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0x40 0x8>;
+	spi-max-frequency = <25000000>;
+	clock-frequency = <50000000>;
+}
