Not much have changed since v6[1] patch series. I did everything
addressed every comment, mostly by robots :), to previous series and
there was one bug fixed in tda998x side. Unless there is any
significant reaction to this series, I am going to put it to rest for
a while now. I have other things to do.
There is currently two other patch series[2][3] that depend on the
first two (ALSA-) patches of this series. The third ("ASoC:
hdmi-codec: Add audio abort() callback for video side to use") is
currently not used and can be dropped if so decided. The rest depends
on those the first two and adds hdmi-audio support for
Beaglebone-black.
Best regards,
Jyri

Changes since v6
* "ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders"
- Add "Acked-by: Arnaud Pouliquen <arnaud.pouliquen@xxxxxx>" and
"Tested-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>", no other changes
* "ALSA: pcm: add IEC958 channel status helper for hw_param"
- Added kernel-doc for snd_pcm_create_iec958_consumer_hw_params()
* "drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT binding"
- Use PTR_ERR_OR_ZERO() in tda998x_audio_codec_init()
- Fix possible uninitialized use of 'size' in tda998x_get_audio_ports()
- Store audio configuration in tda998x_audio_hw_params() instead of
tda998x_configure_audio().
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
