Changes expose several function that are currently unavailable for HDA-DSP drivers for use. Those functions are: snd_hda_codec_cleanup_for_unbind() snd_hda_codec_set_power_save() snd_hda_codec_register() snd_hda_codec_unregister() snd_hda_codec_device_init() This allows upcoming AVS driver [1] to re-use even mode of HDA related code that is currently available in sound/pci/hda and sound/hda and prevent any code duplication within avs-driver that would otherwise had to happen. Last patch in the series provides snd_hdac_ext_bus_link_at() - a helper function which allows for retrieval of HDA segment (link) based on codec address directly. This is simpler than parsing codec-name first to extract the address what is the case for snd_hdac_ext_bus_get_link(). The latter function is updated to re-use newly added one so core logic is not duplicated after the addition. Changes v1 -> v2: - snd_hda_codec_new() now calls snd_hda_codec_device_new() with 'snddev_managed' param set to 'true', reported by Kai [1]: https://lore.kernel.org/all/20211208111301.1817725-1-cezary.rojewski@xxxxxxxxx/ Cezary Rojewski (4): ALSA: hda: Add snd_hdac_ext_bus_link_at() helper ALSA: hda: Update and expose snd_hda_codec_device_init() ALSA: hda: Update and expose codec register procedures ALSA: hda: Expose codec cleanup and power-save functions include/sound/hda_codec.h | 11 +++- include/sound/hdaudio_ext.h | 1 + sound/hda/ext/hdac_ext_controller.c | 31 +++++++--- sound/pci/hda/hda_codec.c | 94 ++++++++++++++++++++--------- sound/pci/hda/hda_local.h | 2 - sound/soc/codecs/hdac_hda.c | 2 +- 6 files changed, 100 insertions(+), 41 deletions(-) -- 2.25.1
