The patch ASoC: SOF: Add DMIC token for unmute gain ramp time has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3 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 7df43911e92aa2137ae77ae60efaa9d6656df3fe Mon Sep 17 00:00:00 2001 From: Seppo Ingalsuo <seppo.ingalsuo@xxxxxxxxxxxxxxx> Date: Wed, 12 Jun 2019 12:01:47 -0500 Subject: [PATCH] ASoC: SOF: Add DMIC token for unmute gain ramp time The settling time of DMIC DC level is both platform and used microphone model specific. The unmute gain ramp is used to conceal most of the large DC level seen in beginning of capture. This patch adds into the DMIC DAI IPC struct a new field called unmute_ramp_time and a new token SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME. The value is the ramp length in milliseconds (ms). The ABI minor version is incremented for this backwards compatible change.
