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 179c2e86328c3d7e07f87f9c45a216cda626e9ee Mon Sep 17 00:00:00 2001 From: Divya Prakash Date: Mon, 2 Apr 2018 12:15:49 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Reset DSP pipe in skl_pcm_hw_free Currently during destroy pipeline the gateway is disabled before DMA completion. This leads to improper draining of data and subsequently causing issues on HD-Audio DMA. Hence added a new pipe reset IPC in skl_pcm_hw_free in which the Gateway Enable(GEN bit) is reset to 0 after DMA completion in skl_pcm_trigger.
