["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>; }; |
