Xilinx SPI controller Device Tree Bindings

Required properties:

• compatible : Should be “xlnx,xps-spi-2.00.a”, “xlnx,xps-spi-2.00.b” or “xlnx,axi-quad-spi-1.00.a”
• reg : Physical base address and size of SPI registers map.
• interrupts : Property with a value describing the interrupt

          number.
  

• interrupt-parent : Must be core interrupt controller

Optional properties:

• xlnx,num-ss-bits : Number of chip selects used.

Example:
axi_quad_spi@41e00000 {
compatible = “xlnx,xps-spi-2.00.a”;
interrupt-parent = <&intc>;
interrupts = <0 31 1>;
reg = <0x41e00000 0x10000>;
xlnx,num-ss-bits = <0x1>;
};
