 | 2 |  | 
 | 3 | Required properties: | 
 | 4 | - cell-index : SPI controller index. | 
 | 5 | - compatible : should be "fsl,spi". | 
 | 6 | - mode : the SPI operation mode, it can be "cpu" or "cpu-qe". | 
 | 7 | - reg : Offset and length of the register set for the device | 
 | 8 | - interrupts : <a b> where a is the interrupt number and b is a | 
 | 9 |   field that represents an encoding of the sense and level | 
 | 10 |   information for the interrupt.  This should be encoded based on | 
 | 11 |   the information in section 2) depending on the type of interrupt | 
 | 12 |   controller you have. | 
 | 13 | - interrupt-parent : the phandle for the interrupt controller that | 
 | 14 |   services interrupts for this device. | 
 | 15 |  | 
 | 16 | Example: | 
 | 17 | 	spi@4c0 { | 
 | 18 | 		cell-index = <0>; | 
 | 19 | 		compatible = "fsl,spi"; | 
 | 20 | 		reg = <4c0 40>; | 
 | 21 | 		interrupts = <82 0>; | 
 | 22 | 		interrupt-parent = <700>; | 
 | 23 | 		mode = "cpu"; | 
 | 24 | 	}; |
