| 5 | Required properties: | |
| 6 | - compatible : Should be "dlg,da7213" | |
| 7 | - reg: Specifies the I2C slave address | |
| 8 | ||
| 9 | Optional properties: | |
| 10 | - clocks : phandle and clock specifier for codec MCLK. | |
| 11 | - clock-names : Clock name string for 'clocks' attribute, should be "mclk". | |
| 12 | ||
| 13 | - dlg,micbias1-lvl : Voltage (mV) for Mic Bias 1 | |
| 14 | [<1600>, <2200>, <2500>, <3000>] | |
| 15 | - dlg,micbias2-lvl : Voltage (mV) for Mic Bias 2 | |
| 16 | [<1600>, <2200>, <2500>, <3000>] | |
| 17 | - dlg,dmic-data-sel : DMIC channel select based on clock edge. | |
| 18 | ["lrise_rfall", "lfall_rrise"] | |
| 19 | - dlg,dmic-samplephase : When to sample audio from DMIC. | |
| 20 | ["on_clkedge", "between_clkedge"] | |
| 955da485 | 21 | - dlg,dmic-clkrate : DMIC clock frequency (Hz). |
