[alsa-devel] [RFC 00/11] ASoC: hdac: Add hdac generic driver

[Subhransu S. Prusty]

HDA devices generically can be modelled with DAPM in ASoC. This
series adds a framework in ASoC to model HDA devices. HDA widgets
are enumerated and one or multiple DAPM widget(s) are created.
Connection list is queried for each widget to identify the
connection between two endpoints and modelled using DAPM graph.

Set of event handlers are defined for each widget type. Based on
DAPM events required verbs are sent to program codec.

Finally a function is exported to query for the device endpoint
configuration to create machine controls.
