Required properties:
- compatible: "brcm,bcm2835-i2s"
-- reg: A list of base address and size entries:
- * The first entry should cover the PCM registers
- * The second entry should cover the PCM clock registers
+- reg: Should contain PCM registers location and length.
+- clocks: the (PCM) clock to use
- dmas: List of DMA controller phandle and DMA request line ordered pairs.
- dma-names: Identifier string for each DMA request line in the dmas property.
These strings correspond 1:1 with the ordered pairs in dmas.
