Enhanced HD Audio capabilities introduced in HD Audio controllers are added in backward compatible way i.e. it does not change the behavior of the controller with respect to HDA Bus and HDA devices.
Since there is no change in the hardware with respect to the HDA bus and HDA device it is more appropriate to represent the same in software as well.
In order to align software representation with hardware it makes more sense to have common data structures across device, bus and driver for both enhanced HDA controllers and legacy HDA controllers.
This patch series removes the hdac_ext_device structure, hdac_ext_bus and hdac_ext_driver data structures so that legacy and enhanced HDaudio capabilities can be handled in a backwards-compatible way without separate definitions.
Once this clean-up is complete, additional patches will allow for HDaudio codec support in an ASoC framework without the need to develop new codec drivers, thereby enabling the use of the Intel DSP on more platforms (currently limited to hdmi).
Changes in v3: - No changes in this series except rebase as there were no comments.
Changes in v2: - First three patches from v1 are merged so not included in this series. - No changes in this series except rebase as there were no comments.
