1 J-Core SPI master
2
3 Required properties:
4
5 - compatible: Must be "jcore,spi2".
6
7 - reg: Memory region for registers.
8
9 - #address-cells: Must be 1.
10
11 - #size-cells: Must be 0.
12
13 Optional properties:
14
15 - clocks: If a phandle named "ref_clk" is present, SPI clock speed
16 programming is relative to the frequency of the indicated clock.
17 Necessary only if the input clock rate is something other than a
18 fixed 50 MHz.
19
20 - clock-names: Clock names, one for each phandle in clocks.
21
22 See spi-bus.txt for additional properties not specific to this device.

24 Example:
25
26 spi@40 {
27 compatible = "jcore,spi2";
28 #address-cells = <1>;
29 #size-cells = <0>;
30 reg = <0x40 0x8>;
31 spi-max-frequency = <25000000>;
32 clocks = <&bus_clk>;
33 clock-names = "ref_clk";
