The patch
ASoC: arizona: Add output power up/down delays for speaker path
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: Charles Keepax ckeepax@opensource.wolfsonmicro.com Date: Tue, 27 Sep 2016 16:35:45 +0100 Subject: [PATCH] ASoC: arizona: Add output power up/down delays for speaker path
The later Arizona parts do run write sequences to power up and down the speaker path as such a delay needs to be inserted into the DAPM sequence to allow this to run. This patch adds appropriate delays into the existing coalesced delay scheme.
