+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 addr=
ess.
+- #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
+
+Child nodes represent devices on the SPI bus
+  See ../spi/spi-bus.txt
+
+Example:
+	ssp1: spi@d4035000 {
+		compatible =3D "marvell,mmp2-ssp";
+		reg =3D <0xd4035000 0x1000>;
