1Xilinx SPI controller Device Tree Bindings 2------------------------------------------------- 3 4Required properties: 5- compatible : Should be "xlnx,xps-spi-2.00.a", "xlnx,xps-spi-2.00.b" or "xlnx,axi-quad-spi-1.00.a" 6- reg : Physical base address and size of SPI registers map. 7- interrupts : Property with a value describing the interrupt 8 number. 9 10Optional properties: 11- xlnx,num-ss-bits : Number of chip selects used. 12- xlnx,num-transfer-bits : Number of bits per transfer. This will be 8 if not specified 13 14Example: 15 axi_quad_spi@41e00000 { 16 compatible = "xlnx,xps-spi-2.00.a"; 17 interrupt-parent = <&intc>; 18 interrupts = <0 31 1>; 19 reg = <0x41e00000 0x10000>; 20 xlnx,num-ss-bits = <0x1>; 21 xlnx,num-transfer-bits = <32>; 22 }; 23 24
