You can implement non-register DAPM widgets - look at the virtual controls in the core, or things using SND_SOC_NOPM.
It means dapm widget will not control the codec directly, right? I.e. Everything will be done by _event?
The framework won't do anything directly, yes.
For simplest the driver, can I not define .dapm_widgets and .dapm_routes? All controls will be done in .controls.
It is mandatory to have at least some DAPM support, not having DAPM was such a constant source of bugs that we stopped supporting it.
