| 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"] |
| 21 | - dlg,dmic-clkrate : DMIC clock frequency (Hz). |
