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 e4e2d2f45284f620eeb9eea25570838b2a42c968 Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Wed, 7 Oct 2015 11:31:52 +0100 Subject: [PATCH] ASoC: Intel: Skylake: Add pipe and modules handlers SKL driver needs to instantiate pipelines and modules in the DSP. The topology in the DSP is modelled as DAPM graph with a PGA representing a module instance and mixer representing a pipeline for a group of modules along with the mixer itself. Here we start adding building block for handling these. We add resource checks (memory/compute) 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 Signed-off-by: Jeeja KP Signed-off-by: Subhransu S.
