[PATCH 1/3] ASoC: Intel: Skylake: Reset DSP Pipelines in prepare

[Sriram Periyasamy]

From: Pardha Saradhi K <pardha.saradhi.kesapragada@intel.com>

An application can choose to call .prepare function
any number of times. In such scenarios, there is a
need to reset the DSP pipeline.

[PATCH 2/3] ASoC: Intel: Skylake: Reset DSP pipe in skl_pcm_hw_free

[Sriram Periyasamy]

From: Divya Prakash <divya1.prakash@intel.com>

Currently during destroy pipeline the gateway is disabled
before DMA completion. This leads to improper draining of
data and subsequently causing issues on HD-Audio DMA.
Hence added a new pipe reset IPC in skl_pcm_hw_free in
which the Gateway Enable(GEN bit) is reset to 0 after
DMA completion in skl_pcm_trigger.

[PATCH 3/3] ASoC: Intel: Skylake: Unify the fw ops for SKL and KBL

[Sriram Periyasamy]

From: Pradeep Tewani <pradeep.d.tewani@intel.com>

SKL and KBL driver used separate set of fw ops for library loading.
However, with the unification of fw binary, use the common set of fw
ops for both

The patch

   ASoC: Intel: Skylake: Reset DSP Pipelines in prepare

has been applied to the asoc tree at

   https://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
