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

-Example:
-	ssp1: spi@d4035000 {
-		compatible = "marvell,mmp2-ssp";
-		reg = <0xd4035000 0x1000>;
-		clocks = <&soc_clocks MMP2_CLK_SSP0>;
