+Required properties:
- compatible : "brcm,cygnus-audio"
- #address-cells: 32bit valued, 1 cell.
- #size-cells: 32bit valued, 0 cell.
- reg : Should contain audio registers location and length
- reg-names: names of the registers listed in "reg" property
Valid names are "aud" and "i2s_in". "aud" contains aset of DMA, I2S_OUT and SPDIF registers. "i2s_in" containsa set of I2S_IN registers.
- clocks: PLL and leaf clocks used by audio ports
- clock-names: names of 3 leaf clocks used by audio ports
Valid names are "ch0_audio", "ch1_audio", "ch2_audio"
- interrupts: audio DMA interrupt number
+SSP Subnode properties: +- reg: The index of ssp port interface to use
- Valid value are 0, 1, 2, or 3 (for spdif)
+Example:
- cygnus_audio: audio@180ae000 {
