1PXA2xx SSP SPI Controller
2
3Required properties:
4- compatible: Must be "marvell,mmp2-ssp".
5- reg: Offset and length of the device's register set.
6- interrupts: Should be the interrupt number.
7- clocks: Should contain a single entry describing the clock input.
8- #address-cells:  Number of cells required to define a chip select address.
9- #size-cells: Should be zero.
10
11Optional properties:
12- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,
13  Documentation/devicetree/bindings/spi/spi-bus.txt
14- spi-slave: Empty property indicating the SPI controller is used in slave mode.
15- ready-gpios: GPIO used to signal a SPI master that the FIFO is filled
16  and we're ready to service a transfer. Only useful in slave mode.
