+* Atmel SSC driver.
+
+Required properties:
+- compatible: "atmel,at91rm9200-ssc" or "atmel,at91sam9g45-ssc"
+ - atmel,at91rm9200-ssc: support pdc transfer
+ - atmel,at91sam9g45-ssc: support dma transfer
+- reg: Should contain SSC registers location and length
+- interrupts: Should contain SSC interrupt
+
+Example:

+ - compatible : "asahi-kasei,ak4104"
+
+ - reg : The chip select number on the SPI bus
+
+Optional properties:
+
+ - reset-gpio : a GPIO spec for the reset pin. If specified, it will be
+ deasserted before communication to the device starts.
+
+Example:
+
+spdif: ak4104@0 {
+ compatible = "asahi-kasei,ak4104";
+ reg = <0>;
+ spi-max-frequency = <5000000>;

+ - atmel,model: The user-visible name of this sound complex.
+ - atmel,audio-routing: A list of the connections between audio components.
+ - atmel,ssc-controller: The phandle of the SSC controller
+ - atmel,audio-codec: The phandle of the WM8731 audio codec
+Optional properties:
+ - pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt
+
+Example:
+sound {
+ compatible = "atmel,at91sam9g20ek-wm8731-audio";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_pck0_as_mck>;

+ "Int MIC", "MICIN";
+
+ atmel,ssc-controller = <&ssc0>;
+ atmel,audio-codec = <&wm8731>;
+};
- reset-gpio: a GPIO spec to define which pin is connected to the chip's
!RESET pin
+ - cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag
+ is enabled.
Examples:
Optional properties:
- ti,dmic: phandle for the OMAP dmic node if the machine have it connected
-- ti,jack_detection: Need to be set to <1> if the board capable to detect jack
+- ti,jack_detection: Need to be present if the board capable to detect jack
insertion, removal.
