Dialog Semiconductor DA7212/DA7213 Audio Codec bindings
======
Required properties:
- compatible : Should be "dlg,da7212" or "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>]
- VDDA-supply : Regulator phandle for Analogue power supply
- VDDMIC-supply : Regulator phandle for Mic Bias
- VDDIO-supply : Regulator phandle for I/O power supply
======
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>;
};
