* msm-dai-mi2s

[First Level Nodes]

Required properties:

 - compatible : "msm-dai-mi2s"

 [Second Level Nodes]

Required properties:

 - compatible : "qcom,msm-dai-q6-mi2s"
 - qcom,msm-dai-q6-mi2s-dev-id: MSM or MDM can use Slimbus or I2S interface to
				transfer data to (WCD9XXX) codec.
				If slimbus interface is used then "msm-dai-q6"
				needs to be filled with correct data for
				slimbus interface.
				The sections "msm-dai-mi2s" is used by MDM or
				MSM to use I2S interface with codec.
				This section is used by CPU driver in ASOC MSM
				to configure MI2S interface. MSM internally
				has multiple MI2S namely Primary, Secondary,
				Tertiary and Quaternary MI2S.
				They are represented with id 0, 1, 2, 3
				respectively.
				The field "qcom,msm-dai-q6-mi2s-dev-id"
				represents which of the MI2S block is used.
				These MI2S are connected to I2S interface.

 - qcom,msm-mi2s-rx-lines:	Each MI2S interface in MSM has one or more SD
				lines. These lines are used for data transfer
				between codec and MSM.
				This element in indicates which output RX lines
				are used in the MI2S interface.

 - qcom,msm-mi2s-tx-lines:  	Each MI2S interface in MSM has one or more SD
				lines. These lines are used for data transfer
				between codec and MSM.
				This element in indicates which input TX lines
				are used in the MI2S interface.

Example:

qcom,msm-dai-mi2s {

* MSM9625 ASoC Machine driver

Required properties:
- compatible : "qcom,mdm9625-audio-taiko"
- qcom,model : The user-visible name of this sound card.
- qcom,audio-routing : A list of the connections between audio components.
  Each entry is a pair of strings, the first being the connection's sink,
  the second being the connection's source.
- qcom,taiko-mclk-clk-freq : Master clock value given to codec. Some WCD9XXX
  codec can run at different mclk values. Mclk value can be 9.6MHz or 12.288MHz.
  This element represents the value for MCLK provided to codec.
- prim-i2s-gpio-ws : Specifies gpio assigned for primary WS I2S pin.
- prim-i2s-gpio-din : Specifies gpio assigned for primary DIN I2S pin.
- prim-i2s-gpio-dout : Specifies gpio assigned for primary DOUT I2S pin.
- prim-i2s-gpio-sclk : Specifies gpio assigned for primary SCLK I2S pin.
- prim-i2s-gpio-mclk : Specifies gpio assigned for MCLK I2S pin.

Example:

sound {
		compatible = "qcom,mdm9625-audio-taiko";
		qcom,model = "mdm9625-taiko-i2s-snd-card";

		qcom,audio-routing =

};

* msm-adsp-loader

Required properties:
 - compatible : "qcom,adsp-loader"
 - qcom,adsp-state:
	It is possible that some MSM use PIL to load the ADSP image. While
	other MSM may use SBL to load the ADSP image at boot. Audio APR needs
	state of ADSP to register and enable APR to be used for sending commands
	to ADSP. so adsp-state represents the state of ADSP to ADSP loader.
	Value of 0 indicates ADSP loader needs to use PIL and value of 2 means
	ADSP image is already loaded by SBL.

Example:

qcom,msm-adsp-loader {
	compatible = "qcom,adsp-loader";
	qcom,adsp-state = <2>;
};

* msm-audio-ion

Required properties:
 - compatible : "qcom,msm-audio-ion"

Optional properties:
 - qcom,smmu-enabled:
        It is possible that some MSM have SMMU in ADSP.  While other MSM use
	no SMMU. Audio lib introduce wrapper for ION APIs. The wrapper needs
        presence of SMMU in ADSP to handle ION APIs differently.
        Presence of this property means ADSP has SMMU in it.

Example:

qcom,msm-audio-ion {
	compatible = "qcom,msm-audio-ion;
	qcom,smmu-enabled;
};
