The patch
ASoC: sun4i-codec: Add support for A31 ADC capture 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: Chen-Yu Tsai wens@csie.org Date: Mon, 7 Nov 2016 18:06:59 +0800 Subject: [PATCH] ASoC: sun4i-codec: Add support for A31 ADC capture path
The A31's internal codec capture path has a mixer in front of the ADC for each channel, capable of selecting various inputs, including microphones, line in, phone in, and the main output mixer.
This patch adds the various controls, widgets and routes needed for audio capture from the already supported inputs on the A31.
