 [Second Level Nodes]

Required properties:

 - compatible : "qcom,msm-dai-q6-mi2s"

				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.

* 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.

Optional properties:
 - qcom,proc-img-to-load;
	This property can be used to override default ADSP
	loading by PIL. Based on string input, different proc is
	loaded. Right now we are adding option "modem"
	for 8916 purpose. Default image will be "adsp" which
	will load LPASS Q6 for other targets as expected.
	"adsp" option need not be explicitly mentioned in
	DTSI file, as it is default option.

Example:

qcom,msm-adsp-loader {
	compatible = "qcom,adsp-loader";
	qcom,adsp-state = <2>;
	qcom,proc-img-to-load = "modem";

Required properties:

	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;
};
