[alsa-devel] [PATCH v9 0/3] HDA: add extended HDA

[Vinod Koul]

New HDA controllers from Intel have extended HDA capabilities like
multilink, pipe processing, SPIB, GTS etc In order to use them we create an
extended HDA bus, controller and stream which uses the extended
configuration

Changes in v9:
- removed snd_hdac_ext_bus_map_codec_to_link
- updated snd_hdac_ext_bus_get_link per Takahsi comment and drop the array
- add index in bus instance

Changes in v8:
- fixed some dead code crept in
- checkpatch cleanup

Changes in v7:
- Feedback from Takashi
- removed the macros for register read/writes
- add new macros for reg update
- fix bus pointer macro
- header cleanup on c/h files
- new device name ehdaudioiDn
- removed flags for ext caps, use pointer only
- moved module info to patch 1
- sparse check on series
- remove codec name in link
