[PATCH v3 15/15] ASoC: fsl: Update fsl-ssi binding doc

[mpa@pengutronix.de (Markus Pargmann)]

Update the fsl-ssi bindings. DMA is no required property anymore and
uses the generic DMA bindings. imx-fiq is a new alternative to DMA

Notes:
    Changes in v3:
     - In previous versions, I removed fsl,playback-dma and capture-dma. But they
       are still in use by fsl_dma.c, so I added them again.

 Optional properties:
 - codec-handle:     Phandle to a 'codec' node that defines an audio
                     codec connected to this SSI.  This node is typically
                     a child of an I2C or other control node.
+- dmas:		    Generic dma devicetree binding as described in
+		    Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names:	    Two dmas have to be defined, "tx" and "rx", if fsl,imx-fiq
+		    is not defined.
+- fsl,imx-fiq:	    Bool property. Use imx-pcm-fiq instead of imx-pcm-dma.
 
 Child 'codec' node required properties:
 - compatible:       Compatible list, contains the name of the codec
