  "iis" is the i2s bus clock and i2s_opclk0, i2s_opclk1 are sources of the root

  clk. i2s0 has internal mux to select the source of root clk and i2s1 and i2s2

  doesn't have any such mux.

- #clock-cells: should be 1, this property must be present if the I2S device

  is a clock provider in terms of the common clock bindings, described in

  ../clock/clock-bindings.txt.

- clock-output-names: from the common clock bindings, names of the CDCLK

  I2S output clocks, suggested values are "i2s_cdclk0", "i2s_cdclk1",

  "i2s_cdclk3" for the I2S0, I2S1, I2S2 devices recpectively.

There are following clocks available at the I2S device nodes:

 CLK_I2S_CDCLK    - the CDCLK (CODECLKO) gate clock,

 CLK_I2S_RCLK_PSR - the RCLK prescaler divider clock (corresponding to the

		    IISPSR register),

 CLK_I2S_RCLK_SRC - the RCLKSRC mux clock (corresponding to RCLKSRC bit in

		    IISMOD register).

Refer to the SoC datasheet for availability of the above clocks.

The CLK_I2S_RCLK_PSR and CLK_I2S_RCLK_SRC clocks are usually only available

in the IIS Multi Audio Interface (I2S0).

Note: Old DTs may not have the #clock-cells, clock-output-names properties

and then not use the I2S node as a clock supplier.

Optional SoC Specific Properties:

- pinctrl-0: Should specify pin control groups used for this controller.

- pinctrl-names: Should contain only one value - "default".

Example:

i2s0: i2s@03830000 {

		<&clock_audss EXYNOS_I2S_BUS>,

		<&clock_audss EXYNOS_SCLK_I2S>;

	clock-names = "iis", "i2s_opclk0", "i2s_opclk1";

	#clock-cells;

	clock-output-names = "i2s_cdclk0";

	samsung,idma-addr = <0x03000000>;

	pinctrl-names = "default";

	pinctrl-0 = <&i2s0_bus>;

					  it can be specified via "clocks" if system has

					  clock node (= common clock), or "system-clock-frequency"

					  (if system doens't support common clock)

					  If a clock is specified, it is

					  enabled with clk_prepare_enable()

					  in dai startup() and disabled with

					  clk_disable_unprepare() in dai

					  shutdown().

Example 1 - single DAI link:

STA32X audio CODEC

The driver for this device only supports I2C.

Required properties:

  - compatible: "st,sta32x"

  - reg: the I2C address of the device for I2C

  - reset-gpios: a GPIO spec for the reset pin. If specified, it will be

		 deasserted before communication to the codec starts.

  - power-down-gpios: a GPIO spec for the power down pin. If specified,

		      it will be deasserted before communication to the codec

		      starts.

  - Vdda-supply: regulator spec, providing 3.3V

  - Vdd3-supply: regulator spec, providing 3.3V

  - Vcc-supply: regulator spec, providing 5V - 26V

Optional properties:

  -  st,output-conf: number, Selects the output configuration:

	0: 2-channel (full-bridge) power, 2-channel data-out

	1: 2 (half-bridge). 1 (full-bridge) on-board power

	2: 2 Channel (Full-Bridge) Power, 1 Channel FFX

	3: 1 Channel Mono-Parallel

	If parameter is missing, mode 0 will be enabled.

	This property has to be specified as '/bits/ 8' value.

  -  st,ch1-output-mapping: Channel 1 output mapping

  -  st,ch2-output-mapping: Channel 2 output mapping

  -  st,ch3-output-mapping: Channel 3 output mapping

	0: Channel 1

	1: Channel 2

	2: Channel 3

	If parameter is missing, channel 1 is chosen.

	This properties have to be specified as '/bits/ 8' values.

  -  st,thermal-warning-recover:

	If present, thermal warning recovery is enabled.

  -  st,thermal-warning-adjustment:

	If present, thermal warning adjustment is enabled.

  -  st,fault-detect-recovery:

	If present, then fault recovery will be enabled.

  -  st,drop-compensation-ns: number

	Only required for "st,ffx-power-output-mode" ==

	"variable-drop-compensation".

	Specifies the drop compensation in nanoseconds.

	The value must be in the range of 0..300, and only

	multiples of 20 are allowed. Default is 140ns.

  -  st,max-power-use-mpcc:

	If present, then MPCC bits are used for MPC coefficients,

	otherwise standard MPC coefficients are used.

  -  st,max-power-corr:

	If present, power bridge correction for THD reduction near maximum

	power output is enabled.

  -  st,am-reduction-mode:

	If present, FFX mode runs in AM reduction mode, otherwise normal

	FFX mode is used.

  -  st,odd-pwm-speed-mode:

	If present, PWM speed mode run on odd speed mode (341.3 kHz) on all

	channels. If not present, normal PWM spped mode (384 kHz) will be used.

  -  st,invalid-input-detect-mute:

	If present, automatic invalid input detect mute is enabled.

Example:

codec: sta32x@38 {

	compatible = "st,sta32x";

	reg = <0x1c>;

	reset-gpios = <&gpio1 19 0>;

	power-down-gpios = <&gpio1 16 0>;

	st,output-conf = /bits/ 8  <0x3>;	// set output to 2-channel

						// (full-bridge) power,

						// 2-channel data-out

	st,ch1-output-mapping = /bits/ 8 <0>;	// set channel 1 output ch 1

	st,ch2-output-mapping = /bits/ 8 <0>;	// set channel 2 output ch 1

	st,ch3-output-mapping = /bits/ 8 <0>;	// set channel 3 output ch 1

	st,max-power-correction;		// enables power bridge

						// correction for THD reduction

						// near maximum power output

	st,invalid-input-detect-mute;		// mute if no valid digital

						// audio signal is provided.
