-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";
