Device tree bindings for Marvell PXA SSP ports

Required properties:

	- compatible:	Must be one of
				mrvl,pxa25x-ssp
				mvrl,pxa25x-nssp
				mrvl,pxa27x-ssp
				mrvl,pxa3xx-ssp
				mvrl,pxa168-ssp
				mrvl,pxa910-ssp
				mrvl,ce4100-ssp

	- reg:		The memory base
	- dmas:		Two dma phandles, one for rx, one for tx
	- dma-names:	Must be "rx", "tx"


Example for PXA3xx:

	ssp0: ssp@41000000 {
		compatible = "mrvl,pxa3xx-ssp";
		reg = <0x41000000 0x40>;
		ssp-id = <1>;
		interrupts = <24>;
		clock-names = "pxa27x-ssp.0";
		dmas = <&dma 13
			&dma 14>;
		dma-names = "rx", "tx";
	};

	ssp1: ssp@41700000 {
		compatible = "mrvl,pxa3xx-ssp";
		reg = <0x41700000 0x40>;
		ssp-id = <2>;
		interrupts = <16>;
		clock-names = "pxa27x-ssp.1";
		dmas = <&dma 15
			&dma 16>;
		dma-names = "rx", "tx";
	};

	ssp2: ssp@41900000 {
		compatibl3 = "mrvl,pxa3xx-ssp";
		reg = <0x41900000 0x40>;
		ssp-id = <3>;
		interrupts = <0>;
		clock-names = "pxa27x-ssp.2";
		dmas = <&dma 66
			&dma 67>;
		dma-names = "rx", "tx";
	};

	ssp3: ssp@41a00000 {
		compatible = "mrvl,pxa3xx-ssp";
		reg = <0x41a00000 0x40>;
		ssp-id = <4>;
		interrupts = <13>;
		clock-names = "pxa27x-ssp.3";
		dmas = <&dma 2
			&dma 3>;
		dma-names = "rx", "tx";
	};
