1 * SPI (Serial Peripheral Interface)
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
13 - interrupt-parent : the phandle for the interrupt controller that
14 services interrupts for this device.
19 compatible = "fsl,spi";
22 interrupt-parent = <700>;
