| - 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>] |
