For different platforms, number of dsp cores can vary. So instead of creating array of size SKL_DSP_CORES_MAX, use num_core in dsp_ops() of the respective platform to allocate core usage counts and states.

This patch adds support to manage additional cores on a demand basis. For instance, if module is set to run on certain core, the particular core is powered up in module init. The same is again powered down in module unload.

The patch

ASoC: Intel: Skylake: Move platform specific init to platform dsp_init()

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

Move ipc_init() from helper function to respective platform's dsp_init() as ipc_init() per platform can be different.

The patch

ASoC: Intel: cnl: add dsp ops for cannonlake

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
