+* LITO ASoC Machine driver
+
+Required properties:
+- compatible : "qcom,lito-asoc-snd".
+- qcom,model : The user-visible name of this sound card.
+- qcom,audio-routing : A list of the connections between audio components.
+- asoc-platform: This is phandle list containing the references to platform device
+		 nodes that are used as part of the sound card dai-links.
+- asoc-platform-names: This property contains list of platform names. The order of
+		       the platform names should match to that of the phandle order
+		       given in "asoc-platform".
+- asoc-cpu: This is phandle list containing the references to cpu dai device nodes
+	    that are used as part of the sound card dai-links.
+- asoc-cpu-names: This property contains list of cpu dai names. The order of the
+		  cpu dai names should match to that of the phandle order given
+		  in "asoc-cpu". The cpu names are in the form of "%s.%d" form,
+		  where the id (%d) field represents the back-end AFE port id that
+		  this CPU dai is associated with.
+- asoc-codec: This is phandle list containing the references to codec dai device
+	      nodes that are used as part of the sound card dai-links.
+- asoc-codec-names: This property contains list of codec dai names. The order of the
+		    codec dai names should match to that of the phandle order given
+		    in "asoc-codec".
+- qcom,codec-aux-devs: This is phandle list containing the references to Auxilary
+		       codec devices.
+
+Optional properties:
+- qcom,msm-mi2s-master: This property is used to inform machine driver
+  if MSM is the clock master of mi2s. 1 means master and 0 means slave. The
+  first entry is primary mi2s; the second entry is secondary mi2s, and so on.
+- qcom,msm-mbhc-hphl-swh: This property is used to distinguish headset HPHL
+  switch type on target typically the switch type will be normally open or
+  normally close, value for this property 0 for normally close and 1 for
+  normally open.
+- qcom,msm-mbhc-gnd-swh: This property is used to distinguish headset GND
+  switch type on target typically the switch type will be normally open or
+  normally close, value for this property 0 for normally close and 1 for
+  normally open.
+- qcom,wsa-max-devs : Maximum number of WSA881x devices present in the target
+- qcom,wsa-devs : List of phandles for all possible WSA881x devices supported for the target
+- qcom,wsa-aux-dev-prefix : Name prefix with Left/Right configuration for WSA881x device
+- qcom,ext-disp-audio-rx: Property to specify if Audio over Display port is supported for the target
+- qcom,wcn-btfm : Property to specify if WCN BT/FM chip is used for the target
+- qcom,mi2s-audio-intf: Property to specify if MI2S interface is used for the target
+- qcom,auxpcm-audio-intf: Property to specify if Aux PCM interface is used for the target
+- qcom,cdc-dmic-gpios : phandle for Digital mic clk and data gpios.
+- qcom,msm_audio_ssr_devs: List the snd event framework clients
+- qcom,afe-rxtx-lb: AFE RX to TX loopback.
+- qcom,tlmm-gpio: TLMM gpio number for corresponding LPASS gpio
+- qcom,lito-is-v2-enabled: Check if lito v2 is enabled as lito v2 has gpio support
+  for swr tx data3 slew rate. Change port params for lito v2.
