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";
}
