4 - compatible: Should be "microchip,pic32mzda-spi".
5 - reg: Address and length of register space for the device.
6 - interrupts: Should contain all three spi interrupts in sequence
7               of <fault-irq>, <receive-irq>, <transmit-irq>.
8 - interrupt-names: Should be "fault", "rx", "tx" in order.
9 - clocks: Phandle of the clock generating SPI clock on the bus.
10 - clock-names: Should be "mck0".
11 - cs-gpios: Specifies the gpio pins to be used for chipselects.
12             See: Documentation/devicetree/bindings/spi/spi-bus.txt
15 - dmas: Two or more DMA channel specifiers following the convention outlined
17 - dma-names: Names for the dma channels. There must be at least one channel
18              named "spi-tx" for transmit and named "spi-rx" for receive.
