Changes since v1 and v2:
  - re-written the subject inline to include relevant prefix

  - Node name changed to spdif@18100e00 to be more generic

  - Added maintainers from Documentation/devicetree/bindings/sound/ who
    should be added to the maintainers list?

  - Drop reg description

  - Drop resets description

  - Added $ref for dai-common.yaml

  - Removed unused dt-bindigs/gpio/gpio.h include

  - Added reset and reset-names in the example

  - changed example hex to be lowercase

-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>;
