+BROADCOM Cygnus Audio I2S/TDM/SPDIF controller
+
+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 a
+ set of DMA, I2S_OUT and SPDIF registers. "i2s_in" contains
+ a 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 {
+ compatible = "brcm,cygnus-audio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x180ae000 0xafd>, <0x180aec00 0x1f8>;
+ reg-names = "aud", "i2s_in";
+ clocks = <&audiopll BCM_CYGNUS_AUDIOPLL_CH0>,
+ <&audiopll BCM_CYGNUS_AUDIOPLL_CH1>,
+ <&audiopll BCM_CYGNUS_AUDIOPLL_CH2>;
+ clock-names = "ch0_audio", "ch1_audio", "ch2_audio";
+ interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_HIGH>;
+
+ ssp0: ssp_port@0 {
+ reg = <0>;
+ status = "okay";
+ };
+
+ ssp1: ssp_port@1 {
+ reg = <1>;
+ status = "disabled";
+ };
+
+ ssp2: ssp_port@2 {
+ reg = <2>;
+ status = "disabled";
+ };
+
+ spdif: spdif_port@3 {
+ reg = <3>;
+ status = "disabled";
+ };
+ };
