This adds helper functions to calculate parameters required for base module format and copier module. A generic module is modelled by base module. Copier module is responsible for getting/sending data to FE (host DMAs) and BE (link HDA DMA, SSP, PDM) This also ads module pin management helpers which help in finding pins to use or freeing them up

A module needs to be instantiated and then connected with other modules. On cleanup we need to disconnect the module. This is achieved by helpers module init, bind and unbind which are added here

SKL driver needs to instantiate pipelines and modules in the DSP. Here we start adding building block for handling these. We add resource checks (memory/mcps) for pipelines, find the modules in a pipeline, init modules in a pipe and lastly bind/unbind modules in a pipe These will be used by pipe event handlers in subsequent patches

From: Jeeja KP jeeja.kp@intel.com

This adds widget event handlers for PRE/POST PMU and PRE/POST PMD event for mixer and pga modules. The SKL topology uses PGA and mixer modules to model a topology and manage that with DSP.

These event handlers invoke pipeline creation, destroy, module creation, module bind, unbind and pipeline bind unbind

Event handler sequencing is implement to target the DSP FW sequence expectations to enable path from source to sink pipe for Playback/Capture.

The patch

ASoC: Intel: Skylake: Remove unused CPU dais

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

From: Jeeja KP jeeja.kp@intel.com Date: Mon, 17 Aug 2015 22:56:44 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Remove unused CPU dais

We need to create CPU DAI for each endpoint instance. For this we should have one DMIC DAI, one HDA DAI and SSP DAI. Thus, DMIC23, HDA-SPK/AMIC was not required so this patch removes them

If processing pipe capability is supported, add DSP support. Adds initialization/free/suspend/resume DSP functionality.
