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

-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>;
