The patch

   ASoC: Intel: Skylake: Add driver structures to be filled from topology manifest

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

Subject: [PATCH] ASoC: Intel: Skylake: Add driver structures to be filled from
 topology manifest

The topology manifest would include module common data including resource
and interface table. The resource table consists of resources required by
the dsp module such as buffer size, cycles per second, number of
input/output pins. And, the interface table consists of pcm parameters per
module which can be referenced later.

So define the structures accordingly to represent topology manifest data in
the driver.
