[PATCH 0/3] ASoC: Intel: kbl: Add Multi-endpoint Playback & Echo Ref support

[PATCH 0/3] ASoC: Intel: kbl: Add Multi-endpoint Playback & Echo Ref support

[Naveen M]

1. Add new FE capabilities to support:
  a. Parallel playback on 2 ports simultaneously
     Define new frontends to enable additional playback port.
     This will be used when platform needs to support multi-playback
     on different ports. Ex: Headset and Speaker simultaneously
  b. Echo reference capture capability
     Certain platforms need reference stream of playback to supplement
     User-space post-processing algorithms. This pin enables platform
     driver to provide such a FE.
2. Add DAI links for parallel playback and echo ref
3. Add map for new DAIs for parallel playback and echo ref

[Mark Brown]

The patch

   ASoC: Intel: kbl: Add map for new DAIs for Multi-Playback & Echo Ref

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
