4 - cell-index : QE SPI subblock index.
7 - compatible : should be "fsl,spi".
8 - mode : the SPI operation mode, it can be "cpu" or "cpu-qe".
9 - reg : Offset and length of the register set for the device
10 - interrupts : <a b> where a is the interrupt number and b is a
15 - interrupt-parent : the phandle for the interrupt controller that
19 - gpios : specifies the gpio pins to be used for chipselects.
20   The gpios will be referred to as reg = <index> in the SPI child nodes.
21   If unspecified, a single SPI device without a chip select can be used.

39 - compatible : should be "fsl,mpc8536-espi".
40 - reg : Offset and length of the register set for the device.
41 - interrupts : should contain eSPI interrupt, the device has one interrupt.
42 - fsl,espi-num-chipselects : the number of the chipselect signals.
