Dialog Semiconductor DA7213 Audio Codec bindings ====== 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>; };
