-STMicroelectronics STM32 S/PDIF receiver (SPDIFRX).

-The SPDIFRX peripheral, is designed to receive an S/PDIF flow compliant with
-IEC-60958 and IEC-61937.
-
-Required properties:
-  - compatible: should be "st,stm32h7-spdifrx"
-  - reg: cpu DAI IP base address and size
-  - clocks: must contain an entry for kclk (used as S/PDIF signal reference)
-  - clock-names: must contain "kclk"

-  - dmas: DMA specifiers for audio data DMA and iec control flow DMA
-    See STM32 DMA bindings, Documentation/devicetree/bindings/dma/stm32-dma.txt

-Optional properties:
