What is DMIC one wire mode? This doesn't sound like something I'd expect to vary at runtime.
It means: 1 PDM data wire carries 2 channel data (rising edge for left and falling edge for right).
I thought that was normal for DMICs - is this selecting between left and right or something?
Not sure what is the common name but use the same context here.
MT6358 accepts up to 2 PDM wires for 2 DMICs. If one wire mode is on, MT6358 only accepts 1 PDM wire. If one wire mode is off, MT6358 merges L/R from 2 PDM wires into 1 I2S-like to SoC.
