Required properties:

• compatible : Should be “dlg,da7213”
• reg: Specifies the I2C slave address

Optional properties:

• clocks : phandle and clock specifier for codec MCLK.

• clock-names : Clock name string for ‘clocks’ attribute, should be “mclk”.

• dlg,micbias1-lvl : Voltage (mV) for Mic Bias 1
  [<1600>, <2200>, <2500>, <3000>]

• dlg,micbias2-lvl : Voltage (mV) for Mic Bias 2
  [<1600>, <2200>, <2500>, <3000>]

• dlg,dmic-data-sel : DMIC channel select based on clock edge.
  [“lrise_rfall”, “lfall_rrise”]

• dlg,dmic-samplephase : When to sample audio from DMIC.
  [“on_clkedge”, “between_clkedge”]

• dlg,dmic-clkrate : DMIC clock frequency (Hz).
  [<1500000>, <3000000>]

Example:

codec_i2c: da7213@1a {
    compatible = "dlg,da7213";
     reg = <0x1a>;

     clocks = <&clks 201>;
    clock-names = "mclk";

    dlg,micbias1-lvl = <2500>;
    dlg,micbias2-lvl = <2500>;

    dlg,dmic-data-sel = "lrise_rfall";
    dlg,dmic-samplephase = "between_clkedge";
    dlg,dmic-clkrate = <3000000>;
};
