+Marvell PXA SSP CPU DAI bindings
+
+Required properties:
+
+ compatible Must be "mrvl,pxa-ssp-dai"
+ port A phandle reference to a PXA ssp upstream device
+
+Optional properties:
+
+ clock-names
+ clocks Through "clock-names" and "clocks", external clocks
+ can be configured. If a clock names "extclk" exists,
+ it will be set to the mclk rate of the audio stream
+ and be used as clock provider of the DAI.
+
+Example:
+
+ /* upstream device */
+
+ ssp1: ssp@41000000 {
+ compatible = "mrvl,pxa3xx-ssp";
+ reg = <0x41000000 0x40>;
+ interrupts = <24>;
+ clock-names = "pxa27x-ssp.0";
+ };
+
+ /* DAI as user */
+
+ ssp_dai0: ssp_dai@0 {
+ compatible = "mrvl,pxa-ssp-dai";
+ port = <&ssp1>;
+ #sound-dai-cells = <0>;
+ };
+
