Why is this in DT as opposed to being configured by the DAPM routing or something - what is the concrete effect of this? Also...
+- realtek,dmic1-data-pin +- realtek,dmic2-data-pin
- Indicate which pin is used for each DMIC.
...should it be combined with these (eg, if one of these properties is specified should that imply that DMIC is enabled)? We should also have something saying what the value for these properties is.
+- realtek,en-jd-func
- Boolean. Indicate if codec IRQ is used or not. It is usually used for JD
- and/or headset button detection.
I'm not sure I understand what this is for? I'd expect that the interrupt would be used if specified, though if a GPIO is specified I guess that'd override it.
