This commit introduces the possibility to have multiple
device nodes attached to the same I2S controller. For this
purpose a new i2s-device.yaml description has been introduced
with the a 'reg' property to define the logic number of the
device. For example, if two microphones are attached to the
same I2S port (say 1) to achieve stereo audio, the two microphones
might be described in dts as:
&i2s1 {
status = "ok";
mic@0 {
compatible = "...";
reg = <0>;
label = "...";
};
mic@1 {
compatible = "...";
reg = <1>;
label = "...";
};
};
