| 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"; | |
| } |
