There is currently two other patch series[1][2] that depend on the
three first (ALSA-) patches of this series. It would be nice to get at
least those three applied sooner rather than later, so please tell me
if I can do anything to get those in.
BTW, I applied the relevant patches from the two series to on top of
this one. Obviously the two series conflicted with each other a bit and
also the IEC958 helper patch from [2] conflicted with the IEC958 patch
from my series (which is weird since Arnaud's series depends on my
series...). After resolving the conflicts everything compiled fine,
but for some reason neither the 'ELD' or IEC958 Playback Default'
appeared on my BBB. I'll try to find time to debug this further at
some point.

Changes since v5
- Rebased on top of the latest drm-next branch
- Allow 32 bit samplewidth in snd_pcm_create_iec958_consumer() and
snd_pcm_create_iec958_consumer_hw_params()
- Propose new simpler DT binding for tda998x audio
- Squash tda998x audio DT binding together with hdmi-codec integration
Changes since RFC v4,
- Rebased on top of the latest drm-next branch
- Split the hdmi-codec abort functionality into a separate patch for
better visibility of what it is all about
- This does not affect the tda998x patches as the abort
functionality is not used
- Drop S18_3* formats from I2S_FORMATS and add a comment about formats
not supported by HDMI
Changes since RFC v3,
ASoC side:
- Add "ALSA: pcm: add IEC958 channel status helper for hw_params"
- Add "tda998x: Improve tda998x_configure_audio() audio related pdata"
- use snd_pcm_create_iec958_consumer_hw_params() to construct the stream header
- Remove set_clk() callback from hdmi-codec. It is not needed for now.
- Refer to stream header in AIF as specified in HDMI standard
- Set current_stream to NULL only after video side audio_shutdown() has
been called. Avoid potential race if video side attempts to abort audio
at the same time.
- No need to have video side device pointer in the hdmi codec's pdata as
it is found from dev->parent.
- Fix hdmi-codec enum: DAI_ID_I2C > DAI_ID_I2S
- Improve audio_startup API comment
- Make improved checkpatch happy
- BUG_ON > WARN_ON
- put */ ending the block comment to a separate line
DRM side:
- Fix tda998x get_eld() locking
- Change tda998x audio parameters in pdata to more generic, that can
be readily used in tda998x_audio_config()
- Rename and restructure audio port related private data members to
be more descriptive
- Require audio configuration trough ASoC hdmi-codec if HDMI audio is
configured trough DT binding.
DTS:
- Increase McASP fifo usage form 1 to 32
