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.

In this patch the SSP0 BE's mode is changed from I2S mode to DSP_B with 8 slots of 16 bits. It enables 4 slot for IV feedback and 2 slots for playback on max98927 for kabylake machine driver
The layout of SSP0 Tx and Rx slots is as follows; 1. Playback uses Tx slots 0 and 1 2. Capture uses Rx slots 4,5,6,7.
Slots 0 through 3 of Rx are used by DMIC codec RT5514 in another flavor of Kabylake platform. We are using the same slots 4 through 7 on all Kabylake platforms for max98927 in order to reuse same NHLT configuration.
