0001 J-Core SPI master
0002
0003 Required properties:
0004
0005 - compatible: Must be "jcore,spi2".
0006
0007 - reg: Memory region for registers.
0008
0009 - #address-cells: Must be 1.
0010
0011 - #size-cells: Must be 0.
0012
0013 Optional properties:
0014
0015 - clocks: If a phandle named "ref_clk" is present, SPI clock speed
0016 programming is relative to the frequency of the indicated clock.
0017 Necessary only if the input clock rate is something other than a
0018 fixed 50 MHz.
0019
0020 - clock-names: Clock names, one for each phandle in clocks.
0021
0022 See spi-bus.txt for additional properties not specific to this device.
0023
0024 Example:
0025
0026 spi@40 {
0027 compatible = "jcore,spi2";
0028 #address-cells = <1>;
0029 #size-cells = <0>;
0030 reg = <0x40 0x8>;
0031 spi-max-frequency = <25000000>;
0032 clocks = <&bus_clk>;
0033 clock-names = "ref_clk";
0034 }
