+- compatible: must be either "allwinner,sun4i-a10-codec" or

+- reg: must contain the registers location and length
+- interrupts: must contain the codec interrupt
+- dmas: DMA channels for tx and rx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: should include "tx" and "rx".

for an active slot as default, and the default active bits are at the LSB of
the masks.

+The explicit masks are given as array of integers, where the first
