1BROADCOM Cygnus Audio I2S/TDM/SPDIF controller
2
3Required properties:
4	- compatible : "brcm,cygnus-audio"
5	- #address-cells: 32bit valued, 1 cell.
6	- #size-cells:  32bit valued, 0 cell.
7	- reg : Should contain audio registers location and length
8	- reg-names: names of the registers listed in "reg" property
9		Valid names are "aud" and "i2s_in". "aud" contains a
10		set of DMA, I2S_OUT and SPDIF registers. "i2s_in" contains
11		a set of I2S_IN registers.
12	- clocks: PLL and leaf clocks used by audio ports
13	- assigned-clocks: PLL and leaf clocks
14	- assigned-clock-parents: parent clocks of the assigned clocks
15		(usually the PLL)
16	- assigned-clock-rates: List of clock frequencies of the
17		assigned clocks
18	- clock-names: names of 3 leaf clocks used by audio ports
19		Valid names are "ch0_audio", "ch1_audio", "ch2_audio"
20	- interrupts: audio DMA interrupt number
21
22SSP Subnode properties:
23- reg: The index of ssp port interface to use
24	Valid value are 0, 1, 2, or 3 (for spdif)
