+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:
+
+- clocks: If a phandle named "ref_clk" is present, SPI clock speed
+ programming is relative to the frequency of the indicated clock.
+ Necessary only if the input clock rate is something other than a
+ fixed 50 MHz.
+
+- clock-names: Clock names, one for each phandle in clocks.
+
+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>;
+ clocks = <&bus_clk>;
+ clock-names = "ref_clk";
+}
