[PATCH 0/5] ASoC: Intel: Skylake: Wov optimizations

[Vinod Koul]

This series starts with two minor fixes on driver to fix a memory leak and
one NULL pointer exception and then adds power optimization to driver for WOV
case by suspending the stream DMA and keeping only DSP pipe and endpoint On
during that case

Dharageswari.R (2):
  ASoC: Intel: Skylake: Fix the NULL pointer exception in dsp_clean up
  ASoC: Intel: Skylake: Prevent sending Set DMA Control IPC if the
    widget is "On"

Jeeja KP (2):
  ASoC: Intel: Skylake: Suspend PCMs when marked as active suspend
  ASoC: Intel: Boards: remove ignore_suspend for WoV streams

Mousumi Jana (1):
  ASoC: Intel: Skylake: Fix memory leak during init instance

The patch

   ASoC: Intel: Skylake: Fix the NULL pointer exception in dsp_clean up

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.

[Vinod Koul]

From: Jeeja KP <jeeja.kp@intel.com>

For 'ignore_suspend' cases we need to keep DSP and pipes On, but
can suspend the stream and pause the DMA as we are not rendering
data during the suspended time.

For this we can check the dai widget ignore_suspend flag in
trigger suspend/resume, and start and stop the host DMA and host
copier pipelines.

[PATCH 5/5] ASoC: Intel: Boards: remove ignore_suspend for WoV streams

[Vinod Koul]

From: Jeeja KP <jeeja.kp@intel.com>

On WoV we can suspend the DMA and keep the DSP pipelines only On,
so remove the ignore_suspend for WoV streams but keep them for
WoV endpoints.

This helps in achieving better power by suspending DMAs

Applied "ASoC: Intel: Boards: remove ignore_suspend for WoV streams" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: Boards: remove ignore_suspend for WoV streams

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: Boards: remove ignore_suspend for WoV streams

On WoV we can suspend the DMA and keep the DSP pipelines only On,
so remove the ignore_suspend for WoV streams but keep them for
WoV endpoints.

This helps in achieving better power by suspending DMAs
