The patch
ASoC: es7134: add es7134 DAC driver
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: Jerome Brunet jbrunet@baylibre.com Date: Mon, 27 Feb 2017 16:47:23 +0100 Subject: [PATCH] ASoC: es7134: add es7134 DAC driver
The es7134 is 24bit, 192Khz i2s DA converter for PCM audio. Datasheet is available here : http://www.everest-semi.com/pdf/ES7134LV%20DS.pdf
This driver is also compatible with the es7144, which is the same as the es7134, with 2 additional pins for filtering capacitors.
