[alsa-devel] [PATCH v2 00/10] Enable HDA Codec support on Intel Platforms (Series2)

[Rakesh Ughreja]

Many Intel platforms (SKL, KBL) etc. in the market supports enhanced 
audio capabilities which also includes DSP processing. This patch carry
forwards the work that is done in the previous series to enable HD Audio
codecs on such platforms.

This patch series adds ASoC HDA codec driver for Intel platforms. It is
written by reusing the legacy HDA ALSA codec driver. Intention is to
maximize the reuse and minimize the changes in the legacy HDA codec driver.

Changes in v2:
- Resolved review comments and rebased to latest kernel.
- added module load support for codec drivers.

Rakesh Ughreja (10):
  ALSA - Ext hda: add wait for codec to respond after link reset
  ASoC: Intel: Boards: Machine driver for Intel platforms
  ASoC: Intel: Skylake: Add entry in sst_acpi_mach for HDA codecs
  ASoC: Intel: Skylake: add HDA BE DAIs
  ASoC: Intel: Skylake: use hda_bus instead of hdac_bus
  ALSA: hda - split snd_hda_codec_new function
  ALSA: hdac: remove memory allocation from snd_hdac_ext_bus_device_init
  ALSA: hdac: add extended ops in the hdac_bus
  ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers
  ASoC: Intel: Boards: add support for HDA codecs
