Audio Binding for Arndale boards

Required properties:

- compatible : Can be the following,

			"samsung,arndale-rt5631"

- samsung,audio-cpu: The phandle of the Samsung I2S controller

- samsung,audio-codec: The phandle of the audio codec

Optional:

- samsung,model: The name of the sound-card

Arndale Boards has many audio daughter cards, one of them is

rt5631/alc5631. Below example shows audio bindings for rt5631/

alc5631 based codec.

Example:

sound {

		compatible = "samsung,arndale-rt5631";

		samsung,audio-cpu = <&i2s0>

		samsung,audio-codec = <&rt5631>;

};

  Boolean. Indicate MIC1/2 input and LOUT1/2/3 outputs are differential,

  rather than single-ended.

- realtek,gpio-config

  Array of six 8bit elements that configures GPIO.

    0 - floating (reset value)

    1 - pull down

    2 - pull up

- realtek,jd1-gpio

  Configures GPIO Mic Jack detection 1.

  Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively.

- realtek,jd2-gpio

- realtek,jd3-gpio

  Configures GPIO Mic Jack detection 2 and 3.

  Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively.

Pins on the device (for linking into audio routes):

  * IN1P

	realtek,pow-ldo2-gpio =

		<&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;

	realtek,in1-differential = "true";

	realtek,gpio-config = /bits/ 8  <0 0 0 0 0 2>;   /* pull up GPIO6 */

	realtek,jd2-gpio = <3>;  /* Enables Jack detection for GPIO6 */

};

   - samsung,s3c6410-i2s: for 8/16/24bit stereo I2S.

   - 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(7.1) I2S with

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

     TDM support. TDM (Time division multiplexing) is to allow transfer of

     multiple channel audio data on single data line.

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

     playback, sterio 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.

   - samsung,exynos7-i2s: with all the available features of exynos5 i2s,

     exynos7 I2S has 7.1 channel TDM support for capture, secondary fifo

     with only external dma and more no.of root clk sampling frequencies.

   - samsung,exynos7-i2s1: I2S1 on previous samsung platforms supports

     stereo channels. exynos7 i2s1 upgraded to 5.1 multichannel with

     slightly modified bit offsets.

- reg: physical base address of the controller and length of memory mapped

  region.

- clocks : the clock provider of SYS_MCLK

- micbias-resistor-k-ohms : the bias resistor to be used in kOmhs

	The resistor can take values of 2k, 4k or 8k.

	If set to 0 it will be off.

	If this node is not mentioned or if the value is unknown, then

	micbias	resistor is set to 4K.

- micbias-voltage-m-volts : the bias voltage to be used in mVolts

	The voltage can take values from 1.25V to 3V by 250mV steps

	If this node is not mentionned or the value is unknown, then

	the value is set to 1.25V.

- VDDA-supply : the regulator provider of VDDA

- VDDIO-supply: the regulator provider of VDDIO

	compatible = "fsl,sgtl5000";

	reg = <0x0a>;

	clocks = <&clks 150>;

	micbias-resistor-k-ohms = <2>;

	micbias-voltage-m-volts = <2250>;

	VDDA-supply = <&reg_3p3v>;

	VDDIO-supply = <&reg_3p3v>;
