- reg: physical base address of the controller and length of memory

- interrupts: interrupt specifier for the fifo.
- clocks: phandle to the fifo peripheral clock provided by the audio
clock controller.
-- resets: phandle to memory ARB line provided by the arb reset controller.
+- resets: list of reset phandle, one for each entry reset-names.
+- reset-names: should contain the following:

- #sound-dai-cells: must be 0.
