[PATCH v2 0/6] ASoC: Intel: Skylake: Add loadable module support for Kabylake

[Subhransu S. Prusty]

KBL module load is a bit different than rest as Library manifest
containing module information is required to be loaded first before
loading module.

So common changes are moved to helpers and arguments are modified as a
pre-work for adding module loading support.

Also, separate dsp_fw_ops is registered and load library for kabylake is
added to use code loader dma for library and module load.

changes in v2:
	- Few minor fixes in comments
	- Fixed the cover letter subject

G Kranthi (2):
  ASoC: Intel: Skylake: Move sst common initialization to a helper
    function
  ASoC: Intel: Skylake: Modify arguments to reuse module transfer
    function

Sodhi, VunnyX (1):
  ASoC: Intel: Skylake: Add loadable module support on KBL platform

Subhransu S. Prusty (3):
  ASoC: Intel: Skylake: Commonize library load
  ASoC: Intel: Skylake: Register dsp_fw_ops for kabylake
  ASoC: Intel: Skylake: Modify load_lib_ipc arguments for a nowait
    version

[PATCH v2 1/6] ASoC: Intel: Skylake: Move sst common initialization to a helper function

[Subhransu S. Prusty]

From: G Kranthi <gudishax.kranthikumar@intel.com>

Some skl sst context are not dependent of platform and initializing them
independently for each platform can lead to errors. So optimize by
moving them to a helper function and platform specific init code can
call this.

[PATCH v2 2/6] ASoC: Intel: Skylake: Commonize library load

[Subhransu S. Prusty]

request firmware, strip extended manifest and release library changes
are common to kabylake and APL.

So move these common code to utils to be reused in later patches for
kabylake library load.

[PATCH v2 3/6] ASoC: Intel: Skylake: Modify arguments to reuse module transfer function

[Subhransu S. Prusty]

From: G Kranthi <gudishax.kranthikumar@intel.com>

Kabylake also uses code loader dma for module load and library load.
skl_transfer_module can be reused. Modify the arguments to include
library index to be passed to lib load ipc and module/lib check to use
correct ipc for lib/module load.

[PATCH v2 4/6] ASoC: Intel: Skylake: Register dsp_fw_ops for kabylake

[Subhransu S. Prusty]

For audio kabylake is same as skylake except the module load approach.
This patch registers different dsp_fw_ops for kabylake and next patch
adds the module load support for kabylake.

[PATCH v2 5/6] ASoC: Intel: Skylake: Modify load_lib_ipc arguments for a nowait version

[Subhransu S. Prusty]

Kabylake uses code loader dma and wait on notification instead of ipc
reply for load library ipc status. So modify the argument of
skl_sst_ipc_load_library to check on flag to wait for ipc reply.

[Mark Brown]

The patch

   ASoC: Intel: Skylake: Add loadable module support on KBL platform

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,

Subject: [PATCH] ASoC: Intel: Skylake: Modify arguments to reuse module
 transfer function

Kabylake also uses code loader dma for module load and library load.
skl_transfer_module can be reused. Modify the arguments to include
library index to be passed to lib load ipc and module/lib check to use
correct ipc for lib/module load.
