[alsa-devel] [PATCH MC Next Gen 0/2] Add mixer and control interface media entities

[Shuah Khan]

This patch series adds the following:

Add support for creating MEDIA_ENT_F_AUDIO_MIXER entity for
each mixer and a MEDIA_INTF_T_ALSA_CONTROL control interface
entity that links to mixer entities. MEDIA_INTF_T_ALSA_CONTROL
entity corresponds to the control device for the card.

Change au0828_create_media_graph() to create pad link between
MEDIA_ENT_F_AUDIO_MIXER entity and decoder's AU8522_PAD_AUDIO_OUT.

This patch series is dependent on an earlier patch series:

Update ALSA, and au0828 drivers to use Managed Media Controller API:
