[Mark Brown]

The patch

   ASoc: Intel: boards: Add WOV as sink for nau88l25_ssm4567 machine

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

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

We have specific constraints for FE device (48KHz, stereo, 16
bits) and fixups for BE DMIC links (2 or 4 ch), so add those.

Also add one more FE DAIlink for dmiccap

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

Applied "ASoC: Intel: Add Nuvoton+Maxim machine driver entry" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: Add Nuvoton+Maxim machine driver entry

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.

I there any reason you keep using inconsistent name for this IC. The
original driver uses "NAU8825" name and the one above is "NAU88L25".

Please keep naming consistent. The driver chip should be names either
NAU8825 or NAU88L25 but it has to be done everywhere.

I had this question to Vinod earlier as well sent NAU88L25 -> NAU8825
rename patch but got no reply.
