[PATCH v1 1/3] ASoC: cygnus: Add EXPORT_SYMBOL for helper function

[Lori Hikichi]

The helper function cygnus_ssp_set_custom_fsync_width() is intended
to be called from an ASoC machine driver, need to export symbol
if using modules.

[PATCH INTERNAL 1/1] ASoC: cygnus: Remove set_fmt from SPDIF dai ops

[Lori Hikichi]

The SPDIF port cannot modify its format so a set_fmt function is not
needed. Previously, we used a generic set_fmt for all ports and returned
an error code for the SPDIF port. It is cleaner to not populate the
set_fmt field.

Please ignore this patch. It was accidentally included in the patch set and is a
duplicate of another patch already in the patch set.

Applied "ASoC: cygnus: Remove set_fmt from SPDIF dai ops" to the asoc tree

[Mark Brown]

The patch

   ASoC: cygnus: Remove set_fmt from SPDIF dai ops

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

[PATCH v1 3/3] ASoC: cygnus: Remove support for 8 bit audio and for mono

[Lori Hikichi]

These modes of operation were not working properly and it is
unclear if the hardware could fully support these modes properly.
There is little to be gained by enabling these modes, therefore,
we will just remove support.

[PATCH v1 3/3] ASoC: cygnus: Remove support for 8 bit audio and for mono

[Lori Hikichi]

These modes of operation were not working properly and it is
unclear if the hardware could fully support these modes properly.
There is little to be gained by enabling these modes, therefore,
we will just remove support.

Applied "ASoC: cygnus: Remove support for 8 bit audio and for mono" to the asoc tree

[Mark Brown]

The patch

   ASoC: cygnus: Remove support for 8 bit audio and for mono

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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
