+Imagination Technologies SPDIF Input Controller
+
+Required Properties:
+
+ - compatible : Compatible list, must contain "img,spdif-in"
+
+ - #sound-dai-cells : Must be equal to 0
+
+ - reg : Offset and length of the register set for the device
+
+ - dmas: Contains an entry for each entry in dma-names.
+
+ - dma-names: Must include the following entry:
+ "rx"
+
+ - clocks : Contains an entry for each entry in clock-names
+
+ - clock-names : Includes the following entries:
+ "sys" The system clock
+
+Optional Properties:
+
+ - resets: Should contain a phandle to the spdif in reset signal, if any
+
+ - reset-names: Should contain the reset signal name "rst", if a
+ reset phandle is given
+
+ - interrupts : Contains the spdif in interrupt, if present
+
+Example:
+
+spdif_in: spdif-in@18100E00 {
+ compatible = "img,spdif-in";
+ reg = <0x18100E00 0x100>;
+ interrupts = <GIC_SHARED 20 IRQ_TYPE_LEVEL_HIGH>;
+ dmas = <&mdc 15 0xffffffff 0>;
+ dma-names = "rx";
+ clocks = <&cr_periph SYS_CLK_SPDIF_IN>;
+ clock-names = "sys";
+ #sound-dai-cells = <0>;
+};
