From: Rakesh Ughreja rakesh.a.ughreja@intel.com

This patch removes the hdac_ext_bus structure. The legacy and enhanced HDaudio capabilities can be handled in a backward-compatible way without separate definitions.

Follow-up patches in this series handle the driver definition.

From: Rakesh Ughreja rakesh.a.ughreja@intel.com

Add machine driver for Intel platforms (SKL/KBL/BXT/APL) with HDA and iDisp codecs. This patch adds support for only iDisp (HDMI/DP) codec. In the following patches support for HDA codecs will be added.

This should work for other Intel platforms as well e.g. GLK,CNL however this series is not tested on all the platforms.

Split snd_hda_codec_new into two separate functions. snd_hda_codec_device_init allocates memory and registers with bus. snd_hda_codec_device_new initialializes the fields and performs snd_device_new. This enables reuse of legacy HDA codec drivers as ASoC codec drivers.

In addition mark some functions with EXPORT_SYMBOL_GPL so that it can be called by ASoC wrapper around the legacy HDA driver (hdac_hda).
