		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
		- assigned-clocks: PLL and leaf clocks
		- assigned-clock-parents: parent clocks of the assigned clocks
		(usually the PLL)
		- assigned-clock-rates: List of clock frequencies of the
		assigned clocks
		- 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>;
		assigned-clocks = <&audiopll BCM_CYGNUS_AUDIOPLL>,
		<&audiopll BCM_CYGNUS_AUDIOPLL_CH0>,
		<&audiopll BCM_CYGNUS_AUDIOPLL_CH1>,
		<&audiopll BCM_CYGNUS_AUDIOPLL_CH2>;
		assigned-clock-parents = <&audiopll BCM_CYGNUS_AUDIOPLL>;
		assigned-clock-rates = <1769470191>,
		<0>,
		<0>,
		<0>;
		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";
		};
		};

		CS53L30 audio CODEC

		Required properties:

		- compatible : "cirrus,cs53l30"

		- reg : the I2C address of the device

		- VA-supply, VP-supply : power supplies for the device,
		as covered in Documentation/devicetree/bindings/regulator/regulator.txt.

		Optional properties:

		- reset-gpios : a GPIO spec for the reset pin.

		- mute-gpios : a GPIO spec for the MUTE pin. The active state can be either
		GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled
		by the driver automatically.

		- cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin.
		0 = Hi-Z
		1 = 1.80 V
		2 = 2.75 V

		- cirrus,use-sdout2 : This is a boolean property. If present, it indicates
		the hardware design connects both SDOUT1 and SDOUT2
		pins to output data. Otherwise, it indicates that
		only SDOUT1 is connected for data output.
		* CS53l30 supports 4-channel data output in the same
		* frame using two different ways:
		* 1) Normal I2S mode on two data pins -- each SDOUT
		* carries 2-channel data in the same time.
		* 2) TDM mode on one signle data pin -- SDOUT1 carries
		* 4-channel data per frame.

		Example:

		codec: cs53l30@48 {
		compatible = "cirrus,cs53l30";
		reg = <0x48>;
		reset-gpios = <&gpio 54 0>;
		VA-supply = <&cs53l30_va>;
		VP-supply = <&cs53l30_vp>;
		};
