Hi,
This series is the next step in componentization. It moves the DAPM support to the component level. This will allow any component to have DAPM widgets and routes, which was previously only possible for CODECs, and will allow any component to have DAPM widgets with controls (i.e. Mixers and MUXs), which was previously only possible for CODECs. At the end of this patchset the DAPM code will have (almost) no dependency on snd_soc_codec or snd_soc_platform and the dependency on snd_soc_component is confined to 4 small helper functions. The only reason why there is still snd_soc_codec/snd_soc_platform dependent code is because there are still a lot of drivers which use widget->codec/platform and dapm->codec/platform. So those still need to be initialized. This will be cleaned up in a separate series and once that's done the codec and platform fields will be removed from the widget and DAPM context struct.
One of the major problems of moving DAPM to the component level is that the DAPM context is directly embedded in the snd_soc_codec and snd_soc_platform structs and there are many drivers directly accessing that embedded field. This means it is not possible to move the field without causing a bit of code churn in the drivers. The patch series solves this by adding two fields to the component struct. One pointer to a DAPM context, which points to the DAPM context that is used by the component. And one DAPM context, which is used as the default if no other DAPM context was provided. Neither of the fields is accessed directly, instead a inline helper function is added that returns the DAPM context for a component. This will make it possible to eventually seamlessly switch over once all direct references to CODEC and platform DAPM contexts have been eliminated.
Depends on topic/component, topic/core, topic/dapm and topic/dt
