Hi,
Now that I have access to a board with codec using multiple digital inputs and
outputs (pcm3168a) I found these two issues with the McASP driver:
- unused pins needs to be set as inactive
- the tdm mask is not set correctly when multiple serializers are enabled and
needed
Regards,
Peter

Unused serializers needs to be configured as INACTIVE, otherwise they will
underflow/overflow when multiple serializers are connected, but some are
not needed for the given stream.

If multiple serializers are connected in the system and the number of
channels will need to use more than one serializer the mask to enable the
serializers were left to 0 if tdm_mask is provided

The patch
ASoC: ti: davinci-mcasp: Set unused serializers as INACTIVE
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
