The tegra3 audio can support 24 and 32 bit sample sizes so add the
option to the tegra30_i2s_hw_params to configure the S24_LE or
S32_LE
formats when requested.

Hello,
This patch breaks audio on Tegra30. I don't see errors anywhere, but
there is no audio and reverting this patch helps. Please fix it.
What is the failure mode? I can try and take a look at this some time
this week, but I am not sure if I have any boards with an actual
useful
audio output?
The failure mode is that there no sound. I also noticed that video
playback stutters a lot if movie file has audio track, seems something
times out during of the audio playback. For now I don't have any
more info.
Oh, I didn't say how to reproduce it.. for example simply playing
big_buck_bunny_720p_h264.mov in MPV has the audio problem.
https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_h264.mov
Given that the audio drivers uses regmap, it could be good to dump the
I2S/AHUB registers while the clip if playing with and without this patch
to see the differences. I am curious if the audio is now being played as
24 or 32-bit instead of 16-bit now these are available.
You could also dump the hw_params to see the format while playing as
well ...
$ /proc/asound/<scard-name>/pcm0p/sub0/hw_params
I suppose it is also possible that the codec isn't properly doing >16
bits and the fact we now offer 24 and 32 could be an issue. I've not
got anything with an audio output on it that would be easy to test.
I thought I had tested on a Jetson TK1 (Tegra124) but it was sometime
back. However, admittedly I may have only done simple 16-bit testing
with speaker-test.
We do verify that all soundcards are detected and registered as expected
during daily testing, but at the moment we don't have anything that
verifies actual playback.
Please take a look at the attached logs.
I wonder if we are falling into FIFO configuration issues with the
non-16 bit case.
Can you try adding the following two patches?

If the CIF is not configured as 16 or 8 bit, then the
packing for 8/16 bits should not be enabled as the
hardware only supports 8 or 16 bit packing.

Subject: [PATCH 1/2] ASoC: tegra: config fifos on hw_param changes
If the hw_params uses a different bit or channel count, then we
need to change both the I2S unit's CIF configuration as well as
the APBIF one.
To allow changing the APBIF, add a call to reconfigure the RX or
TX FIFO without changing the DMA or allocation, and get the I2S
driver to call it once the hw params have been calculate.
