-* Qualcomm Technologies LPASS CPU DAI binding
-
-Low-Power Audio SubSystem (LPASS) consist of MI2S interfaces for audio data
-transfer on external codec. LPASS cpu driver is a common code to configure
-MI2S related CPU dai's across different version of LPASS architecture.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: compatible string corresponds to lpass variants driver
- must be "qcom, lpass-cpu-sc7180" for sc7180 lpass

-= MI2S DAIs (Digial Audio Interface)
-"dais" child node of the lpass node. It represents mi2s dais, each mi2s dai is
-subnode of "dais" representing board specific dai setup & required dai clocks.
-"dais" node should have following properties.
-
