3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible       : "fsl,imx-audio-es8328"
5*4882a593Smuzhiyun- model            : The user-visible name of this sound complex
6*4882a593Smuzhiyun- ssi-controller   : The phandle of the i.MX SSI controller
7*4882a593Smuzhiyun- jack-gpio        : Optional GPIO for headphone jack
8*4882a593Smuzhiyun- audio-amp-supply : Power regulator for speaker amps
9*4882a593Smuzhiyun- audio-codec      : The phandle of the ES8328 audio codec
10*4882a593Smuzhiyun- audio-routing    : A list of the connections between audio components.
11*4882a593Smuzhiyun                     Each entry is a pair of strings, the first being the
12*4882a593Smuzhiyun		     connection's sink, the second being the connection's
13*4882a593Smuzhiyun		     source. Valid names could be power supplies, ES8328
14*4882a593Smuzhiyun		     pins, and the jacks on the board:
