+Freescale Synchronous Serial Interface
+
+The SSI is a serial device that communicates with audio codecs.  It can
+be programmed in AC97, I2S, left-justified, or right-justified modes.
+
+Required properties:
+- compatible      : compatible list, containing "fsl,ssi"
+- cell-index      : the SSI, <0> = SSI1, <1> = SSI2, and so on
+- reg             : offset and length of the register set for the device
+- interrupts      : <a b> where a is the interrupt number and b is a
+                     field that represents an encoding of the sense and
+                    level information for the interrupt.  This should be
+                    encoded based on the information in section 2)
+                    depending on the type of interrupt controller you
+                    have.
+- interrupt-parent : the phandle for the interrupt controller that
+                     services interrupts for this device.
+- fsl,mode        : the operating mode for the SSI interface
+                    "i2s-slave" - I2S mode, SSI is clock slave
+                    "i2s-master" - I2S mode, SSI is clock master
+                    "lj-slave" - left-justified mode, SSI is clock slave
+                    "lj-master" - l.j. mode, SSI is clock master
+                    "rj-slave" - right-justified mode, SSI is clock slave
+                    "rj-master" - r.j., SSI is clock master
+                    "ac97-slave" - AC97 mode, SSI is clock slave
+                    "ac97-master" - AC97 mode, SSI is clock master
+
+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.
+
+Child 'codec' node required properties:
+- compatible      : compatible list, contains the name of the codec
+
+Child 'codec' node optional properties:
+- clock-frequency  : The frequency of the input clock, which typically
+                     comes from an on-board dedicated oscillator.
