 - audio-codec		 : the first entry should be phandle of the wm5110 audio

			   codec node, as described in ../mfd/arizona.txt;

			   the second entry should be phandle of the HDMI

			   transmitter node

 - i2s-controller	 : the list of phandle and argument tuples pointing to

			   the second one I2S1

 - audio-amplifier	 : the phandle of the MAX98504 amplifier

   - samsung,s5pv210-i2s: for 8/16/24bit multichannel(5.1) I2S with

     secondary fifo, s/w reset control and internal mux for root clk src.

   - samsung,exynos5420-i2s: for 8/16/24bit multichannel(5.1) I2S for

     playback, sterio channel capture, secondary fifo using internal

     playback, stereo channel capture, secondary fifo using internal

     or external dma, s/w reset control, internal mux for root clk src

     and 7.1 channel TDM support for playback. TDM (Time division multiplexing)

     is to allow transfer of multiple channel audio data on single data line.

  These strings correspond 1:1 with the ordered pairs in dmas.

- clocks: Handle to iis clock and RCLK source clk.

- clock-names:

  i2s0 uses some base clks from CMU and some are from audio subsystem internal

  i2s0 uses some base clocks from CMU and some are from audio subsystem internal

  clock controller. The clock names for i2s0 should be "iis", "i2s_opclk0" and

  "i2s_opclk1" as shown in the example below.

  i2s1 and i2s2 uses clocks from CMU. The clock names for i2s1 and i2s2 should

- #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.

- clock-output-names (deprecated): 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 respectively.

There are following clocks available at the I2S device nodes:

 CLK_I2S_CDCLK    - the CDCLK (CODECLKO) gate clock,

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.

in the IIS Multi Audio Interface.

Note: Old DTs may not have the #clock-cells property and then not use the I2S

node as a clock supplier.

Optional SoC Specific Properties:

  sub system(used in secondary sound source).

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

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

- #sound-dai-cells: should be 1.

Example:

		<&clock_audss EXYNOS_I2S_BUS>,

		<&clock_audss EXYNOS_SCLK_I2S>;

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