		Required properties:
		- compatible : "qcom,msm8x16-audio-codec"
		- qcom,model : The user-visible name of this sound card.
		- qcom,msm-snd-card-id : This id is used to recognize the sound card number
		- qcom,msm-codec-type : This property is used to recognize the codec type
		internal or external.
		- pinctrl-names : Pincntrl entries to configure the PDM gpio lines accordingly
		- pinctrl-0 : This exoplains the active state of the PDM gpio lines
		- pinctrl-1 : This exoplains the suspend state of the PDM gpio lines
