[alsa-devel] Applied "ASoC: wcd9335: Fix build" to the asoc tree
by Mark Brown 01 Aug '18

01 Aug '18

The patch ASoC: wcd9335: Fix build has been applied to the asoc tree at https://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 b74fd69043262003c5b7ce545e59f5a7234ab290 Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie(a)kernel.org> Date: Wed, 1 Aug 2018 14:22:56 +0100 Subject: [PATCH] ASoC: wcd9335: Fix build This reverts commit e57d4ca882e28 (ASoC: wcd9335: add support to wcd9335 codec) due to build failures caused by missing dependencies.

[alsa-devel] [PATCH v2] ASoC: soc-pcm: Use delay set in component pointer function
by Akshu Agrawal 01 Aug '18

01 Aug '18

Take into account the base delay set in pointer callback. There are cases where a pointer function populates runtime->delay, such as: ./sound/pci/hda/hda_controller.c ./sound/soc/intel/atom/sst-mfld-platform-pcm.c This delay was getting lost and was overwritten by delays from codec or cpu dai delay function if exposed.

The patch ASoC: qcom: dt-bindings: Add sdm845 machine bindings has been applied to the asoc tree at https://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.

I did more test base on different Intel platform, and result is the same. Maybe I made some mistake? Can you do the test in yours platform? Thank you!

[alsa-devel] [PATCH] ASoC: soc-pcm: Use delay set in pointer function
by Akshu Agrawal 01 Aug '18

01 Aug '18

There are cases where a pointer function populates runtime->delay, such as: ./sound/pci/hda/hda_controller.c ./sound/soc/intel/atom/sst-mfld-platform-pcm.c Also, in some cases cpu dai used is generic and the pcm driver needs to set delay. This delay was getting lost and was overwritten by delays from codec or cpu dai delay function if exposed.
