Requred properties:

+ p) 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.
+
+
More devices will be defined as this spec matures.
